Mark Backman 012ef41ff4 Redesign UserIdleController to use BotStoppedSpeakingFrame ...

Replace the continuous heartbeat-based timer (UserSpeakingFrame/BotSpeakingFrame
+ asyncio.Event loop) with a simple one-shot timer that starts when
BotStoppedSpeakingFrame is received and cancels on UserStartedSpeakingFrame or
BotStartedSpeakingFrame. This eliminates false idle triggers caused by gaps
between the user finishing speaking and the bot starting to speak (LLM/TTS
latency).

Guard the timer start with two conditions to prevent false triggers:
- User turn in progress: during interruptions, BotStoppedSpeaking arrives
  while the user is still speaking mid-turn.
- Function calls in progress: FunctionCallsStarted arrives before
  BotStoppedSpeaking because the bot speaks concurrently with the function
  call starting, so the timer must wait for the result and subsequent bot
  response.
