(Major change) main() function completely refactored into helpers. _init_controllers now handles decoupled initialization. _process_audio loop logic was fixed to correctly initialize wake words on startup.
Replaced sounddevice with soundcard, removed the audio Queue, added the new download directory to the search path, and added the device listing arguments
Removed all argparse.add_argument() calls, except for the new --config flag. The main() function now calls load_config_from_json() at startup. All internal logic now references the config object (e.g., config.app.name) instead of the old args object.
Fix MpvMediaPlayer Race Condition
Goal: The mpv library runs in its own thread. When a track finishes, its callback (_on_idle_active) runs in that thread and tries to modify the satellite's state, creating a race condition. We will fix this by "marshaling" that callback onto the main asyncio loop.
added loop=loop to the MpvMediaPlayer constructors
Adds command-line arguments (--mqtt-host, --mqtt-port, etc., and --num-leds) to configure the MQTT connection and initial LED setup.
Instantiates and starts the MqttController on application startup if an MQTT host is provided.
Includes the MicMuteHandler class, which listens for mute commands, updates the global mic_muted state, and clears the audio queue on unmute to prevent processing stale audio.
Updates the process_audio loop to respect the mic_muted flag.
Implements the core mute functionality.
Adds a new MicMuteHandler class that subscribes to the set_mic_mute event. This handler updates the state.mic_muted flag and publishes secondary mic_muted or mic_unmuted events for LED feedback.
Modifies the process_audio function to check the state.mic_muted flag in its main loop, pausing audio processing when the flag is True.
Modifies the startup sequence to read the volume_level from the loaded preferences.
This saved value is then passed as the initial_volume when creating the music_player and tts_player instances.
Passes the event_bus and loop instances into the ServerState object upon creation.
Adds new command-line arguments (--led-interface, --led-clock-pin, --led-data-pin) to allow the user to select and configure the LED hardware interface at runtime.
