Replaces the single-root-pattern sequencer with a Track[] array that allows multiple patterns to loop independently. Adds ADD_TRACK (0x0A), REMOVE_TRACK (0x0B), PLAY_TRACKS (0x0C), and SET_TRACK_MUTE (0x0D) protocol records. The C backend gains per-track pending_subs and a tracks_mutex. The Node server gains track-state APIs (/api/tracks/:id/ active, mute, solo) and the frontend shows per-pattern track/mute/solo buttons in the sidebar list.
