Start the output stream paused and only play when TX packets
arrive. Pause again when the packet queue drains to prevent
continuous ALSA buffer underruns (EPIPE errno -32) on Linux.

Use subsecond nanosecond jitter to return a varying signal strength
(2-8) from the dummy backend instead of a static value of 5.

Set server_callsign and server_version on the rig state so they
are included in snapshots sent to clients. Default callsign is
N0CALL when not configured.

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.

Add AudioConfig to server configuration with support for RX capture
and TX playback via cpal and Opus encoding. Run a dedicated TCP
listener (default port 4533) that sends StreamInfo on connect, streams
RX Opus frames to clients, and receives TX frames back.

Add a JSON-over-TCP listener so trx-client can connect to trx-server.
Speaks the ClientEnvelope/ClientResponse protocol from trx-core::client.
- New listener.rs module with per-client connection handling
- ListenConfig/AuthConfig in config.rs (default: 127.0.0.1:4532)
- CLI args --listen and --port for override
- Optional token-based authentication
- Updated example config with [listen] section

Register a dummy rig backend that holds state in memory and responds
to all CAT commands immediately. Useful for development and testing
without hardware.

Move the frontend and backend crate trees to live physically under their
respective binary crate directories, grouping related code together
without merging crate boundaries. Also flatten sub-crate nesting by
moving them out of src/ subdirectories into direct children.

Delete trx-bin (all-in-one) and trx-bin-common (shared lib). Each binary
now has its own config, plugins, and helper modules inlined.
- trx-server: backend-only daemon with ServerConfig (general, rig, behavior)
no frontend dependencies
- trx-client: remote client with ClientConfig (general, remote, frontends)
includes all frontend support (http, rigctl, http-json, qt)
- Dedicated config files: trx-server.toml / trx-client.toml
