Audio-only mpv core on every platform (dedicated com.plezy/mpv_audio_player channels): parameterized android/windows/ linux mpv plugins and a new apple MpvAudioPlayerCore, all skipping video/window paths (vid=no, audio-display=no, gapless-audio=weak). MusicPlaybackService drives an in-memory queue with shuffle/repeat, file-loaded-event gapless arming (property edges coalesce and the android bridge drops them), per-track progress reporting, OS media controls, audio focus, sleep timer, and error auto-skip. PlaybackCoordinator enforces one live native player: starting video disposes the audio core first.
