Root cause: recv_loop started before open_voice completed, bridge
connection died during UI transition. Now setup completes first.

Ant Afu tends to give long replies which causes TTS queue delays.
Append "请用2-3句话简短回答" to reduce response length.

Model outputs 44100Hz but device expects 24000Hz via Opus. Without
resampling, audio plays at wrong speed causing 29s delays between
segments. Verified: synthesis+resample takes 0.38s for 1.6s audio.

Benchmark: short=0.37s, long=1.06s with 8 CPU threads.
GPU not available in pip sherpa-onnx, CPU is fast enough.

- Filter "完成资料引用" and other status text from Antaf responses
- Use int8 quantized model for faster TTS inference
- Add configurable num_threads for sherpa-onnx

ASR wraps user speech as JSON {"content":"...", "language":"zh", "emotion":"..."},
extract only the content field instead of sending raw JSON to Antaf bridge.

The xiaozhi server injects tool_call reminders and system prompts as
role=user messages into dialogue. These were being picked up as the
"last user message" and sent to Antaf bridge instead of the actual query.

Ant Afu returns internal reasoning/thinking process mixed with actual
response text, causing TTS to read out internal monologue. Also fixes
duplicate text chunks being sent repeatedly.

Two approaches to replace self-hosted Qwen3-32B with Ant Afu AI:
- Plan A: Custom LLM Provider (text API via Frida HTTP Bridge)
- Plan B: Full voice passthrough (audio injection via voice bridge)
