Fix camera/mic interference: detection runs during TTS, 12s exit threshold, require no recent commands

- Remove isSpeaking outer guard — detection loop now runs always so lastFaceSeen stays current
- While isSpeaking + no face detected: refresh lastFaceSeen to prevent exit timer ticking during TTS
- Raise no-face exit threshold from 3s to 12s — sporadic missed frames no longer kill the session
- Add noCommandMs guard: camera never exits voice mode within 12s of last spoken command
- Voice auto-trigger still respects isSpeaking (wont reactivate mid-response)
