time::interval() fires its first tick immediately. Recreating it on
every loop iteration made the select! always resolve instantly,
turning the main polling loop into a busy-loop (~13% CPU idle).
Replace with a Box::pin(sleep()) that is only reset after it
completes or when the poll duration changes (rx/tx transition).

Instead of running the cpal input stream continuously, start it
paused and only activate when broadcast subscribers are present.
When the last client disconnects, pause the stream and sleep at
100ms intervals polling for new receivers.
This eliminates idle CPU usage from continuous CoreAudio callbacks,
channel allocations, and sample processing when nobody is listening.

Enable audio streaming by default in AudioConfig.
Fix panic in audio playback thread caused by calling
tokio::runtime::Handle::current() from a plain std::thread.
Use rx.blocking_recv() instead, which is the correct API for
consuming a tokio mpsc receiver from a synchronous context.

Move window._opusDecoder, window._txEncoder, window._nextPlayTime
into closure-scoped variables to avoid polluting the global namespace.
Add showHint() helper to debounce status hint text, preventing
multiple button handlers from fighting over powerHint.textContent.
Throttle audio level indicator updates to max 10/sec instead of
updating on every Opus packet (~50/sec).
Hide audio controls row if the server has no audio configured
(checks /audio endpoint on load).

Add a 120-second TX safety timeout that auto-releases PTT if no mic
data flows (browser crash, disconnect). Timer resets on each audio
callback. Shows countdown in status when < 10s remaining.
Add beforeunload handler that releases PTT via navigator.sendBeacon
when the browser tab is closed during TX.
Detect WebCodecs support on page load and show "Audio requires
Chrome/Edge" on non-Chromium browsers instead of silently failing.
Remove dead playBuffer/playNode variables that were declared but
never used. Fix TX AudioData to always use mono (channel 0) with
numberOfChannels: 1 matching the f32-planar format.

Replace #[tokio::main] with a manual fn main() that builds the tokio
runtime explicitly. All async initialization moves into async_init().
When the appkit frontend is requested, the runtime context is entered
on the main thread and run_appkit_main_thread() is called directly,
giving AppKit thread 0 as required by MainThreadMarker. Ctrl+C is
handled via a spawned task that calls process::exit.
When appkit is not requested, behaviour is unchanged: block on Ctrl+C.

Extract the AppKit event loop from FrontendSpawner::spawn_frontend into
a new public run_appkit_main_thread() function that blocks on the
calling thread. This allows the process main thread (thread 0) to drive
the UI, which is required for MainThreadMarker::new() to succeed.
The FrontendSpawner impl now only spawns the async state watcher task.

Add a new trx-frontend-appkit crate using objc2 + AppKit as a
replacement for the removed Qt/QML frontend. The frontend provides
the same feature set: frequency/mode/band display, PTT/power/VFO/lock
controls, signal/TX metering, and frequency/mode/TX-limit input.
Architecture splits platform-agnostic model (model.rs) from AppKit
UI (ui.rs) to facilitate future UIKit porting. State flows from the
async tokio watcher via std::sync::mpsc to the AppKit main thread;
button actions flow back through a channel to stay on the UI thread.
Feature-gated behind `appkit-frontend` cargo feature.
