Adds info-level logs at each stage of the audio pipeline to help
diagnose why playback produces no audible output:
- FFmpeg first PCM data received
- FFmpeg process exit code
- FFmpeg stderr (errors/HTTP/stream info at info level)
- First opus frame encoded and emitted
- First voice packet sent to TeamSpeak
- Error catching in frame encoding loop

Avoid repeated filesystem checks on every play() call by resolving
the ffmpeg binary path once at module load. Also verify execute
permission after chmod to handle noexec mounts.

The bundled ffmpeg-static binary may lose execute permission after npm
install on some platforms, causing EACCES errors during playback. Now
checks and fixes the permission automatically before spawning ffmpeg.

Implement BiliBiliProvider for video-as-audio playback using direct
BiliBili API calls (search, video info, DASH audio URL extraction).
Add QR code login support and cookie persistence. Update FFmpeg to
send Referer header for BiliBili CDN URLs. Extend platform union type
to "netease" | "qq" | "bilibili" across all interfaces. Add -b flag
for chat commands and B站 badge in web UI.

- 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

Users no longer need to install FFmpeg separately — it is now bundled as
an npm dependency (ffmpeg-static). player.ts resolves the bundled binary
automatically and falls back to system PATH. start.bat and a new
setup.bat script handle dependency installation and project building.

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

- High-precision frame loop using performance.now() tracking
- PCM-level volume control (live adjustable, no FFmpeg restart)
- Proper buffer drain on track end
- Fixes audio quality and playback speed issues
