Two-pronged fix for the state drift between the system notification
(ground truth) and the WebView player bar:
JS (player.js): onTrackChanged now reconciles the incoming index with a
synchronous NSBridge.getState() call before applying it. Stale callbacks
from earlier rapid skips immediately correct themselves to the live
settled index instead of overwriting the correct state.
Kotlin (MusicService.kt): debounce JS-initiated transitions (seek /
setQueue) by 120 ms so rapid skip sequences produce one onTrackChanged
notification at the final index rather than one per skip step. Auto-advance
transitions are still fired immediately since JS doesn't initiate those.
