Christian Gick 6c1073e79d fix(vad): remove competing AudioStream that caused intermittent VAD failures ...

The _count_frames coroutine created a second rtc.AudioStream on the caller's
audio track, competing with AgentSession's internal pipeline for event loop
time. Under load, this caused VAD to miss speech → user_state stuck on "away".

- Remove _count_frames AudioStream (debugging artifact)
- Add VAD state diagnostics (speaking count, away duration)
- Add VAD watchdog: warns if user_state=away >30s (MAT-40 detection)

Fixes: MAT-40
