Bugs fixed:
- play-at: stop current playback before jumping to queue index
- playNext retry: use break instead of return to ensure stateChange emits
- sendVoiceData: skip if disconnecting to avoid errors during teardown
UI: player-left and lyrics button now toggle lyrics page (open/close)

- Add isAdvancing guard to playNext() to prevent concurrent calls from
skipping songs (trackEnd + user !next race condition)
- Replace removeAllListeners in WebSocket setup with tracked named
listeners, attach only once per bot instead of every 5 seconds
- Add .catch() to unhandled playNext() in cmdVote
- Add sessionId counter to AudioPlayer to discard stale setTimeout
callbacks after stop()+play() transitions
- Defer nulling TS3 client until disconnect() promise resolves
- Add null checks for providers in play-by-id and add-by-id endpoints
- Add PCM buffer backpressure (pause FFmpeg at 960KB, resume at 480KB)
- Change volume slider from @input to @change to avoid flooding server
- Wrap error-reporting sendTextMessage in try/catch to prevent
unhandled rejection in error handler
- Clamp elapsed getter to song duration
- Log FFmpeg stderr at debug level instead of swallowing
- Return null from prev() in Sequential mode instead of wrapping

Two bugs prevented auto-advance:
1. FFmpeg close handler was empty — ChildProcess object persisted after
close, so frame loop check `!this.ffmpeg` never triggered trackEnd
2. playNext() is async (resolves URL) but trackEnd handler didn't catch
rejected promises, causing silent failures

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
