- Replace Kyutai TTS with macOS say (16 kHz mono FR);
NPC voice map _SAY_VOICE_MAP; helper _tts_say_sync
- Local vllm-mlx :8520 as primary LLM (_chat_one),
ailiance as fallback, spoken phrase as last resort;
_chat_reply never raises (loop stays alive on 502)
- Pad 800 ms silence before /transcribe (_pad_wav_silence)
to prevent last-word truncation
- Background _keep_llm_warm ping every 600 s (cold start)
- Root log level INFO; X-Zacus-Heard/Said headers
- test_chat_reply: empty_choices expects spoken fallback
