-xiaozhi-server 握手基准测试脚本（异步 drain 版）
-
-模拟 digital-human 客户端最小握手路径：
-  ws 连接 → 发 hello(features.mcp=true) → 收 welcome
-       → 发 listen detect "嘿，你好呀" → 收 wake word TTS 音频
-       → 响应 MCP initialize / tools/list
-
-与原版差异：
-- recv_data 放到后台线程持续 drain，所有 frame 入队（带时间戳）
-- 主循环从队列取 frame：binary 帧丢弃，text 帧立即解析处理
-- 模拟 digital-human websocket.js 异步 onmessage 行为
-- binary 帧不再阻塞主循环对 text frame 的处理（虽然 FIFO 顺序不变，
-  但确保 bench 不再因 settleout 等待而漏掉 tools/list 帧）
-
-指标：
-  t_hello_to_first_audio   : hello 发送 → 第一帧 TTS 音频（binary）抵达
-  t_hello_to_tools_ready   : hello 发送 → server 下发 tools/list 请求抵达
-
-用法：
-  python benchmark/handshake_bench.py --runs 10 --url ws://localhost:8000/xiaozhi/v1/
