- FishTTS: restructured to one websocket call per utterance, sends done_speaking signal after real audio duration has elapsed (not generation time). Uses PCM sample count to calculate exact playback duration.
- TalkTool: tracks speaking state, rejects new talk calls with error while still speaking. Clears on done_speaking signal from TTS.
- Both done_speaking sender/receiver are optional for backward compat.
