Issue 1 (MusicService): wrap DefaultHttpDataSource in CacheBitmapLoader so
Media3 notification artwork is fetched once and served from memory on every
subsequent auto-advance. warmArtworkCache() pre-loads current+next 3 tracks
on both onMediaItemTransition and onTimelineChanged (queue replace via setQueue).
Adds explicit media3-datasource dependency.
Issue 2 (back button): replace deprecated onKeyDown with OnBackPressedCallback.
WebBridge.setOverlayState(bool) tracks whether JS has an overlay open;
consumeBackPress() is called first — if true, MainActivity delegates to
window.NSPlayer.handleBack() which closes the topmost layer. Falls back to
webView.goBack() then moveTaskToBack(true) so the MusicService binding survives.
JS side: _syncOverlayState() + MutationObserver keep the native flag current;
handleBack covers NP overlay, queue panel, action sheet, all modals, sidebar.

- Replace legacy MediaBrowserServiceCompat/MediaSessionCompat with
Media3 MediaSessionService (MusicService.kt) + ExoPlayer set to
WAKE_MODE_NETWORK — holds WakeLock + WifiLock through Doze so audio
plays uninterrupted on locked screen
- Media3 manages the notification; no manual NotificationCompat.Builder
→ no disappear/reappear flicker when skipping tracks
- Full bidirectional bridge:
JS → native: window.NSBridge.* (WebBridge.kt, 13 methods)
Native → JS: window.NSPlayer.* callbacks (onReady, onTrackChanged,
onPositionUpdate, onPlaybackStateChanged, onQueueEnded, onError)
- player.js: progressive enhancement — all playback routes through
NSBridge when running inside the wrapper, falls back to S.audio on
plain PWA/browser; removes all window.Android.* calls
- main.js: guard _onForeground mediaSession playbackState setter behind
!window.NSBridge so native Media3 session is never stomped
- ProGuard rules updated to keep WebBridge @JavascriptInterface methods
and Media3 classes
- bridge-test.html: manual integration test page for every bridge method
