The bot's own VOICE_STATE_UPDATE showed server-level deaf:true — a
server-deafened member is NOT sent the streamer's audiovisual RTP by Discord,
which is the likely reason no H264 arrives despite the DAVE watch reaching
Ready. The previous fire-and-forget forceSelfServerUnmuteUndeafen() ran once
after the first Ready join and silently reverted on reconnect/restart.
- Export forceSelfServerUnmuteUndeafen from recorder.ts; re-assert it (with
read-back verification logging stillDeaf) at the START of every
startStreamWatch() before STREAM_WATCH is sent (dynamic import avoids the
recorder <-> videoRecorder <-> streamWatchReceiver module cycle).
- Re-assert it again after a successful voice reconnect.
- startStreamWatch() is now async; callers use void.
