Radio 1.2.0
Playback rewritten on the SDK's detached-audio model — one shared session that survives the tool losing foreground.
Fixes:
- Bluetooth icon now opens Bluetooth settings
- Bluetooth play/pause actions the current station
- stop → exit → play resumes the same station
- no more double playback (one player, one session)
- stream no longer stops ~10s after screen off / tool inactive
