docs: update README — accurate feature list + Android native app description

Removed:
- "WebView wrapper" — Android is native Jetpack Compose, not a WebView
- "Artwork pre-warming / pre-buffer on cold start" — not implemented this way
- ABS chapters/speed/sleep/progress on Android — web only for now

Added:
- Lyrics section: lrclib.net, fallback chain, in-memory cache, synced scroll
- Android: last played song in MiniPlayer across restarts
- Android: ABS library browser tab (hidden until configured)
- Android: no login flash on startup
- Settings: connection status dots, save button top+bottom, matched web order
- Multi-artist support in NowPlaying
- Artist cards with images in search
- Genre browsing
- ABS web vs Android split into separate entries
- Accurate Android project structure
