refactor: extract typed auto bandwidth estimator

The runner image's `reuse` failed to import (NoEncodingModuleError): it
needs an encoding-detection backend, which the bare `reuse` install does
not provide and which libmagic/`file` is not present to satisfy. Install
`reuse[charset-normalizer]` so the reuse job can run in the image.

Rebuild the runner image and recreate the containers to pick this up.

+# Podman-based Gitea Actions runners
+
+Run two independent Gitea Actions runners on one host as rootless Podman
+containers managed by systemd (Quadlet) — one per project — instead of two
+VMs. Uses the **host executor**: workflow steps run directly inside a
+purpose-built runner image that already has the Rust toolchain and all build
+dependencies baked in, so CI runs skip the per-run install cost and no
+Docker/Podman socket is needed.
+
+## Files
+
+| File | Purpose |
+|------|---------|
+| `Containerfile` | Runner image: Debian + build deps + clang + Rust + Node + `reuse` + `act_runner`. |
+| `entrypoint.sh` | Registers on first boot (if needed), then runs the daemon. |
+| `config.yaml` | act_runner config template (seeded into each runner's volume). |
+| `trx-rs-runner.container` | Quadlet unit for the trx-rs runner. |
+| `project2-runner.container` | Quadlet unit for the second project's runner. |
+
+## Prerequisites (once per host)
+
+Rootless Podman with cgroups v2 (default on modern distros). As the unprivileged
+user that will own the runners:
+
+```bash
+# Survive logout / start on boot without an interactive session.
+loginctl enable-linger "$USER"
+```
+
+No `podman.socket` is required for the host executor.
+
+## 1. Build the image
+
+```bash
+cd container
+podman build -t trx-rs-ci:latest .
+```
+
+## 2. Get a registration token
+
+For **each** repo: *Settings → Actions → Runners → Create new Runner* and copy
+the token. (Org- or instance-level tokens work too if you prefer wider scope.)
+
+## 3. Install and start the runners
+
+```bash
+mkdir -p ~/.config/containers/systemd
+cp trx-rs-runner.container project2-runner.container ~/.config/containers/systemd/
+
+# Paste each repo's token for the FIRST boot only:
+#   Environment=GITEA_RUNNER_REGISTRATION_TOKEN=xxxx…
+$EDITOR ~/.config/containers/systemd/trx-rs-runner.container
+$EDITOR ~/.config/containers/systemd/project2-runner.container
+
+systemctl --user daemon-reload
+systemctl --user start trx-rs-runner
+systemctl --user start project2-runner
+
+systemctl --user status trx-rs-runner
+podman logs -f gitea-runner-trx-rs
+```
+
+Once each runner shows **online** in the repo's runner list, blank out the
+`GITEA_RUNNER_REGISTRATION_TOKEN` line again (the registration is persisted in
+the `…-data` volume) and `systemctl --user daemon-reload`.
+
+## Required workflow change: the `reuse` job
+
+The host executor runs steps directly in the container and therefore **cannot
+run Docker-based actions**. The current `reuse` job uses `fsfe/reuse-action@v5`,
+which is a Docker action. `reuse` is baked into the image, so replace that job
+with a plain command:
+
+```yaml
+  reuse:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: REUSE compliance
+        run: reuse lint
+```
+
+The `lint` and `test` jobs need no changes: their `sudo apt-get …` and rustup
+steps still run, but become fast no-ops because the image already has those
+packages and the toolchain. (`sudo` is included in the image for exactly this
+reason.)
+
+> If you would rather keep Docker-based actions and per-run images, use the
+> **Docker executor** instead: drop the `:host` suffix from the label in
+> `config.yaml`, enable `systemctl --user --now enable podman.socket`, mount it
+> into the container, and set `container.docker_host` to the socket path. That
+> trades the baked-in speed for stronger per-job isolation.
+
+## Tuning
+
+- **`capacity`** (in `config.yaml`) — concurrent jobs per runner. Rust builds
+  are heavy; 1–2 is sensible when two runners share a host.
+- **`PodmanArgs=--cpus/--memory`** (in each `.container`) — hard resource caps
+  so one project cannot starve the other.
+- **SELinux** — the `:Z` volume flag is already set; keep it if SELinux is
+  enforcing.
+

+# TypeScript migration baseline
+
+This baseline records the browser architecture at the start of the migration.
+It is intentionally historical; generated output sizes are tracked separately
+by the deterministic frontend build.
+
+## Startup order
+
+The initial document loads these scripts in order:
+
+1. `/vendor/opus-decoder-0.7.11.min.js`
+2. `/vendor/leaflet.js`
+3. `/leaflet-ais-tracksymbol.js`
+4. `/webgl-renderer.js`
+5. `/ui-core.js`
+6. `/app.js`
+
+Decoder and feature scripts are then loaded lazily by the inline loader in
+`index.html`. The frontend smoke test locks the core ordering and rejects
+remote script or stylesheet URLs.
+
+## Source measurements
+
+At baseline, first-party JavaScript comprised 23 files and approximately
+776 KiB. The largest sources were:
+
+| Source | Bytes |
+|---|---:|
+| `app.js` | 337,111 |
+| `map-core.js` | 131,899 |
+| `plugins/scheduler.js` | 60,883 |
+| `plugins/bookmarks.js` | 30,543 |
+| `plugins/sat.js` | 22,541 |
+| `plugins/vchan.js` | 20,195 |
+| `webgl-renderer.js` | 18,993 |
+
+The migrated source snapshot contained 123 distinct direct `window.*`
+assignments. These are compatibility callbacks, shared state, and plugin entry
+points. New TypeScript code must not add to that set; the typed plugin registry
+and explicit services replace it over the course of the migration.
+
+All production scripts, stylesheets, fonts, icons, and map assets were already
+served from local embedded routes. The automated startup test ensures no
+remote runtime script or stylesheet dependency is introduced.

+# TypeScript Migration Plan
+
+> **Scope**: `src/trx-client/trx-frontend/trx-frontend-http/`
+>
+> **Status**: Proposed
+
+## 1. Decision
+
+Migrating the web frontend to TypeScript is worthwhile, provided it is used to
+remove implicit contracts and global coupling. Renaming JavaScript files to
+`.ts` without changing their boundaries would add tooling without delivering
+the main safety benefits.
+
+The migration must be incremental. Every intermediate commit and pull request
+must leave the frontend buildable and usable.
+
+## 2. Current State
+
+The frontend currently contains roughly 21,700 lines of first-party
+JavaScript. Its largest components include:
+
+- `app.js`: approximately 8,900 lines;
+- `map-core.js`: approximately 3,500 lines;
+- `plugins/scheduler.js`: approximately 1,500 lines;
+- `plugins/bookmarks.js`: approximately 800 lines;
+- `plugins/vchan.js`: approximately 560 lines.
+
+Important characteristics of the current architecture are:
+
+- scripts are embedded individually into the Rust binary with `include_str!`;
+- the Rust HTTP server exposes an explicit route for each asset;
+- plugins are loaded dynamically as classic scripts;
+- script order is significant;
+- modules communicate through `window.*`, `window.trx`, callbacks, and shared
+  mutable state;
+- the main HTML file contains the plugin loader;
+- a Web Worker is loaded through a fixed URL;
+- Cargo builds do not require Node.js;
+- CI images contain Node.js, but CI currently runs only Rust and REUSE checks;
+- Leaflet, Opus decoder, fonts, images, and other vendored assets are local.
+
+These constraints make a big-bang rewrite unnecessarily risky.
+
+## 3. Goals
+
+The migration should:
+
+1. Create checked contracts between Rust responses and browser code.
+2. Replace global callbacks with explicit module interfaces.
+3. Split `app.js` by responsibility.
+4. Make rig, capability, decoder, scheduler, audio, and spectrum state explicit.
+5. Preserve lazy loading for expensive features.
+6. Add frontend type checking, linting, and automated tests to CI.
+7. Keep ordinary Cargo builds independent of Node.js and network access.
+8. Preserve existing browser behavior throughout the migration.
+
+## 4. Non-Goals
+
+The migration will not initially:
+
+- introduce a UI framework;
+- redesign the user interface;
+- convert vendored JavaScript to TypeScript;
+- change REST, SSE, WebSocket, or worker protocols unless required to make an
+  existing contract unambiguous;
+- make `build.rs` install packages or download frontend dependencies;
+- convert all of `app.js` in one pull request.
+

+    ├── style.css
+    └── themes.css
+```
+
+The exact feature directories may evolve, but dependencies should point from
+features toward `core` and `api`, never from `core` back into features.
+
+## 6. Tooling
+
+Use TypeScript for type checking and esbuild for bundling. A framework-specific
+development server is not needed.
+
+Recommended compiler baseline:
+
+```json
+{
+  "compilerOptions": {
+    "target": "ES2022",
+    "module": "ESNext",
+    "moduleResolution": "Bundler",
+    "strict": true,
+    "noUncheckedIndexedAccess": true,
+    "exactOptionalPropertyTypes": true,
+    "useUnknownInCatchVariables": true,
+    "noEmit": true,
+    "lib": ["ES2022", "DOM"]
+  }
+}
+```
+
+Worker code should use a separate configuration with `WebWorker` rather than
+`DOM` globals.
+
+The package scripts should provide at least:
+
+```text
+npm run typecheck
+npm run lint
+npm test
+npm run build
+npm run verify-generated
+```
+
+Pin dependencies in `package-lock.json`. New package and generated files must
+carry or inherit valid REUSE licensing information.
+
+## 7. Cargo and Asset Integration
+
+Cargo must remain usable on machines without Node.js. Do not invoke `npm`
+automatically from `build.rs`.
+
+The initial integration should work as follows:
+
+1. TypeScript and JavaScript sources live under `frontend/src`.
+2. esbuild writes browser-ready output under `assets/web/generated`.
+3. Generated browser output is committed to the repository.
+4. Rust embeds generated output, not TypeScript source.
+5. CI rebuilds the frontend and fails if committed output is stale.
+
+During early phases, retain the existing public URLs, including:
+
+```text
+/app.js
+/ui-core.js
+/map-core.js
+/scheduler.js
+/decode-history-worker.js
+```
+
+Keeping these URLs stable avoids coupling the first migration phases to changes
+in HTML loading, authentication rules, caching, or Rust routing.
+
+After modules and code splitting are established, replace the explicit list of
+Rust constants and handlers with an embedded generated-asset directory. The
+server must still enforce an allowlist, correct MIME types, cache headers, and
+path traversal protection.
+
+## 8. Rust-to-TypeScript Contracts
+
+Generate TypeScript definitions from Rust wire types instead of maintaining
+parallel handwritten representations.
+
+Initial candidates include:
+
+- `RigState`, `RigInfo`, and `RigCapabilities`;
+- the `/rigs` response;
+- decoder registry entries;
+- scheduler configuration and status;
+- filter and spectrum state;
+- recorder responses;
+- SSE update payloads;
+- decoded-message variants;
+- WebSocket control and status messages.
+
+A generator such as `ts-rs` can produce
+`frontend/src/api/generated.ts`. Generated definitions should describe only
+wire formats. UI state and view models should remain handwritten.
+
+CI must regenerate these definitions and fail when the working tree changes.
+Serde renames, tagged enums, optional fields, flattened values, and numeric
+ranges must be checked explicitly during the initial generator integration.
+
+TypeScript types do not validate data at runtime. Critical compatibility
+boundaries should retain focused runtime checks for missing or malformed data,
+particularly when clients and servers may run different versions.
+
+## 9. Target Module Contracts
+
+Plugins should eventually implement an explicit interface rather than assigning
+callbacks to `window`:
+
+```ts
+interface TrxPlugin {
+  readonly id: string;
+  initialize(context: PluginContext): void | Promise<void>;
+  dispose?(): void;
+}
+
+interface PluginContext {
+  api: TrxApi;
+  events: TrxEventBus;
+  navigation: NavigationService;
+  notifications: NotificationService;
+  state: ReadonlyRadioState;
+}
+```
+
+During the transition, `legacy/global-bridge.ts` may expose the minimum globals
+required by unmigrated scripts. The bridge must shrink as migration progresses;
+new feature code must not add new global callbacks.
+
+State should be divided by responsibility rather than replaced by one large
+typed global:
+
+```ts
+interface RadioState {
+  activeRigId: string | null;
+  capabilities: RigCapabilities | null;
+  connection: ConnectionState;
+  frequencyHz: number | null;
+  mode: RigMode | null;
+  bandwidthHz: number | null;
+}
+
+interface AudioState {
+  rx: AudioStreamState;
+  tx: AudioStreamState;
+  volume: VolumeState;
+}
+
+interface DecoderState {
+  registry: DecoderDescriptor[];
+  status: ReadonlyMap<DecoderId, DecoderStatus>;
+}
+```
+
+Commands should receive a rig ID explicitly. They must not infer their target
+from mutable global selection state after an asynchronous operation begins.
+
+## 10. Migration Phases
+
+### Phase 0: Baseline and Measurements
+
+- Record current asset names, sizes, and load order.
+- Add a browser startup smoke test.
+- Record existing global symbols and plugin callbacks.
+- Confirm that generated bundles do not introduce remote runtime dependencies.
+
+**Exit criterion:** current behavior and asset loading have an automated
+baseline.
+
+### Phase 1: Tooling Scaffold
+
+- Add the frontend package, lockfile, TypeScript configuration, and esbuild.
+- Allow existing JavaScript as build input without type checking it globally.
+- Produce fixed-name outputs matching current URLs.
+- Add frontend commands and CI checks.
+- Document local frontend development commands.
+
+**Exit criterion:** existing JavaScript passes through the frontend build with
+no runtime changes, and CI detects stale generated output.
+
+### Phase 2: Generated API Types
+
+- Add Rust-to-TypeScript type generation.
+- Generate the first status, rig, capability, and decoder contracts.
+- Introduce a typed fetch/post client and typed SSE decoding boundary.
+- Keep narrow runtime guards at compatibility boundaries.
+
+**Exit criterion:** new API consumers cannot use untyped response objects.
+
+### Phase 3: Core Browser Services
+
+Convert or create:
+
+- DOM lookup helpers;
+- notifications and confirmations;
+- settings and per-rig preferences;
+- navigation;
+- the event bus;
+- application state stores;
+- plugin registry and loader.
+
+Convert `ui-core.js` as the first strict TypeScript entry.
+
+**Exit criterion:** shared UI behavior is TypeScript, tested, and does not add
+new globals.
+
+### Phase 4: Independent Leaf Modules
+
+Convert lower-coupling code first:
+
+1. WebGL renderer;
+2. decode-history worker;
+3. screenshot support;
+4. FT2 and FT4;
+5. WSPR;
+6. CW and other decoder views.
+
+Workers must be separate build entries.
+
+**Exit criterion:** each converted module has typed inputs, outputs, and tests.
+
+### Phase 5: Plugin Loading
+
+- Move the inline loader out of `index.html`.
+- Replace classic-script injection with typed dynamic imports.
+- Register plugins through `TrxPlugin`.
+- Preserve lazy loading by tab and feature.
+- Remove the corresponding global callbacks after each plugin migrates.
+
+**Exit criterion:** plugin dependencies and loading order are represented by the
+module graph rather than implicit script order.
+
+### Phase 6: Split the Main Application
+
+Extract `app.js` by responsibility:
+
+1. authentication and API transport;
+2. rig enumeration and switching;
+3. radio commands and capabilities;
+4. audio streaming;
+5. spectrum state and rendering;
+6. decode history;
+7. recorder;
+8. keyboard shortcuts;
+9. application bootstrap.
+
+Do not split by arbitrary line ranges. Each extraction must establish an
+explicit interface and remove the corresponding globals.
+
+**Exit criterion:** the bootstrap file composes services and features but does
+not contain their implementations.
+
+### Phase 7: High-Coupling Features
+
+Convert the remaining large features after the core contracts are stable:
+
+- scheduler and satellite scheduler;
+- bookmarks;
+- virtual channels;
+- map and map-backed statistics;
+- remaining decoder plugins.
+
+**Exit criterion:** no first-party classic scripts or untyped plugin callbacks
+remain.
+
+### Phase 8: Asset-Server Consolidation
+
+- Enable code splitting and hashed chunks.
+- Embed the generated asset directory in Rust.
+- Serve generated assets through a generic, allowlisted handler.
+- Add appropriate immutable caching for hashed output.
+- Retain stable handling for HTML and version metadata.
+- Remove obsolete fixed-asset constants and handlers.
+
+**Exit criterion:** Rust no longer needs a source edit for every generated
+frontend chunk.
+
+### Phase 9: Strictness and Cleanup
+
+- Remove `allowJs`.
+- Remove the legacy global bridge.
+- Enable all selected strict compiler and lint rules.
+- Remove obsolete generated compatibility bundles.
+- Update architecture and contributor documentation.
+
+**Exit criterion:** all first-party frontend source is strict TypeScript and the
+browser runtime exposes only intentionally documented globals.
+
+## 11. Testing Strategy
+
+Frontend CI should run:
+
+```sh
+npm ci
+npm run typecheck
+npm run lint
+npm test
+npm run build
+git diff --exit-code -- assets/web/generated frontend/src/api/generated.ts
+```
+
+Testing should cover four layers:
+
+1. **Pure unit tests** for bandwidth calculations, formatting, state changes,
+   capability decisions, and message routing.
+2. **DOM component tests** for dialogs, tabs, workspace selection, rig
+   switching, and collapsible control sections.
+3. **Worker tests** for decode-history pruning, batching, and message formats.
+4. **Browser smoke tests** for startup, authentication gating, plugin loading,
+   navigation, rig switching, audio controls, and map initialization.
+
+The existing dependency-free `ui-core` test can remain during the scaffold
+phase. It should be moved to the standard TypeScript test runner once that
+runner is established.
+
+## 12. CI Changes
+
+Add a dedicated frontend job rather than hiding frontend work inside the Cargo
+jobs. The job should:
+
+- use the Node.js version provided by the runner image;
+- run with `npm ci`, never a mutable install;
+- cache the npm download cache, not `node_modules`;
+- type-check, lint, test, and build;
+- verify generated artifacts and Rust-generated types are current;
+- run REUSE validation after generated files are produced.
+
+Rust lint and test jobs should continue to consume committed generated assets.
+
+## 13. Pull Request Strategy
+
+Use small, independently reversible pull requests. A recommended sequence is:
+
+1. tooling and unchanged JavaScript build;
+2. generated Rust wire types and typed API client;
+3. `ui-core` conversion;
+4. worker and WebGL conversion;
+5. decoder plugin conversions in small groups;
+6. plugin registry and dynamic imports;
+7. one `app.js` responsibility per PR;
+8. scheduler, bookmarks, and map conversions;
+9. generic embedded asset serving;
+10. removal of JavaScript compatibility mode.
+
+Every PR should include:
+
+- runtime behavior preserved or intentionally documented;
+- frontend type checking and tests;
+- strict Rust formatting and Clippy;
+- generated-artifact drift verification;
+- no newly introduced undocumented `window` globals;
+- no remote runtime asset dependency.
+
+## 14. Risks and Mitigations
+
+### Superficial Conversion
+
+**Risk:** globals receive declarations but remain coupled and mutable.
+
+**Mitigation:** require every converted module to expose explicit inputs and
+outputs and remove at least the globals it replaces.
+
+### Cargo Becomes Dependent on Node
+
+**Risk:** builds fail on systems without Node or network access.
+
+**Mitigation:** commit deterministic generated output and keep npm outside
+`build.rs`.
+
+### Script-Order Regressions
+
+**Risk:** switching to modules changes execution timing and scope.
+
+**Mitigation:** retain current public entries initially, then replace script
+loading only after the plugin registry is in place.
+
+### Unreviewable `app.js` Rewrite
+
+**Risk:** a large conversion is difficult to review, test, or bisect.
+
+**Mitigation:** extract one responsibility at a time and keep bootstrap working
+after every extraction.
+
+### Rust and Browser Contracts Drift
+
+**Risk:** TypeScript compiles against stale wire definitions.
+
+**Mitigation:** generate types from Rust and enforce a clean working tree after
+generation in CI.
+
+### Generated Asset Noise
+
+**Risk:** committed bundles make reviews noisy.
+
+**Mitigation:** separate source and generated commits when useful, include
+source maps, and require deterministic output.
+
+### Bundle or Startup Regression
+
+**Risk:** bundling loads too much code eagerly.
+
+**Mitigation:** record the current baseline, preserve feature-level lazy loads,
+and track entry/chunk sizes in CI.
+
+## 15. Initial Proof of Concept
+
+The first implementation PR should be deliberately limited to:
+
+1. adding the frontend package and locked toolchain;
+2. building existing JavaScript to fixed-name generated output;
+3. adding frontend CI and drift checks;
+4. generating initial rig/status TypeScript definitions;
+5. introducing the typed API client;
+6. converting `ui-core.js` to strict TypeScript;
+7. preserving every existing asset URL and observable behavior.
+
+This proof of concept is the decision gate for the remainder of the migration.
+If it materially improves contract safety without making Cargo development
+unwieldy, continue with the phased plan. If it does not, the repository can
+retain the tooling and the converted core without committing to a full rewrite.
+
+## 16. Completion Criteria
+
+The migration is complete when:
+
+- all first-party browser source is strict TypeScript;
+- vendor files remain isolated and declared through narrow type adapters;
+- Rust wire types generate their browser contracts;
+- no feature depends on accidental script ordering;
+- no undocumented mutable `window` callbacks remain;
+- `app.js` has been replaced by a small typed bootstrap and feature modules;
+- frontend type checking, linting, unit tests, component tests, browser smoke
+  tests, and generated-output checks run in CI;
+- Cargo builds remain possible without Node.js or network access;
+- production assets remain local, embedded, cacheable, and reproducible.
