Subject: [PATCH] Update __main__.py

Imported the new ButtonController.

In _init_controllers():

Instantiated ButtonController when config.button.enabled is True.

Passed loop, event_bus, state, and config.button.

Stored the instance on state.button_controller to keep it alive for the lifetime of the process.

Left the rest of startup orchestration unchanged (audio engine, MQTT, LEDs, etc.), so the button is just an additional input surface plugged into the existing architecture.
