fix: interview stuck after first question - listener restart race condition

- finishSpeaking was checking !isListening which could already be true
  from recognition.onend auto-restart, preventing startListening()
- Now force-stops stale recognition, resets isListening=false, then
  restarts with 200ms delay to avoid collision with onend handler
- Added debug logging for listener restart flow
