Christian Gick 3bf9229ae4 fix(MAT-56): Prevent bot silence from STT noise leak + LLM timeout ...

Three fixes for the bot going silent after ~10 messages:

1. STT artifact handler now returns early — previously detected noise
   leaks ("Vielen Dank.", etc.) but still appended them to transcript,
   inflating context until LLM timed out after 4 retries.

2. Context truncation — caps LLM chat context at 40 items and internal
   transcript at 80 entries to prevent unbounded growth in long sessions.

3. LLM timeout recovery — watchdog detects when agent has been silent
   for >60s despite user activity, sends a recovery reply asking user
   to repeat their question instead of staying permanently silent.
