Progress/lyrics sync:
- AudioPlayer tracks framesPlayed (ground truth: frames * 20ms + seekOffset)
- BotStatus.elapsed is the real elapsed from server
- Frontend polls GET /elapsed every 3s for ground truth
- Client interpolates between syncs (serverElapsed + timeSinceSync)
- Pause freezes at interpolated value, resume resyncs from server
- No more client-side timestamp drift
Playlist play all:
- Stops current playback before loading
- Respects play mode: random/rloop picks random first song, seq plays first

- AudioPlayer.seek() restarts FFmpeg with -ss parameter for actual seeking
- New POST /api/player/:botId/seek endpoint
- BotStatus includes seekOffset and playStartTime from server
- Frontend elapsed = seekOffset + (now - playStartedAt)
- Progress bar click now seeks to clicked position
- All timing actions use _resetTiming() helper with seekOffset
- Lyrics sync uses store.elapsed which includes seekOffset

Follows TS3AudioBot-NetEaseCloudmusic-plugin pattern:
- QueuedSong.url is now optional (metadata-only queue entries)
- resolveAndPlay() fetches URL on-demand right before playback
- Playlist/album/FM load instantly (only metadata stored)
- playNext() resolves URL lazily, skips up to 3 songs on failure
- Avoids expired URLs for songs deep in the queue
