The audio listener was ignoring the CLI --listen override and always
binding to the config default (127.0.0.1), making it unreachable
from remote clients.

Replace the rolling canvas signal graph with a practical signal
measurement feature. The operator can start/stop measurement to
collect signal samples, then view averaged and peak S-unit results.
Also fix signal display to correctly convert dBm wire format to
S-units using standard S-meter scale (S1=-121dBm, S9=-73dBm,
6dB per S-unit).

time::interval() fires its first tick immediately. Recreating it on

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.

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

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.
