手势识别改用纯OpenCV实现，无额外依赖

docs: update PROJECT_PLAN.md with gesture detection (Phase 21)

feat: add more gestures (thumbs_down, fist, peace, ok, pointing_up)

feat: add gesture detection (thumbs up, open palm) with MediaPipe

docs: update changelog with latest fixes

fix: replace non-existent clear_output_buffer with stop_playing

fix: reduce tap-to-wake default threshold to 0.5g (most sensitive)

调整人脸追踪补偿: pitch=9度(向下), yaw=-7度(向右)

fix: 优化退出机制，减少shutdown超时

fix: 修正yaw补偿方向（-5度）

fix: 添加yaw补偿（向左5度），修复机器人偏向用户右边的问题

fix: 修正pitch补偿方向（正值向下看）

fix: 添加人脸追踪pitch偏移补偿（向下7度）

refactor: 使用SDK的compose_world_offset进行正确的pose组合

fix: 修复euler顺序和Sendspin音频播放

fix: 修复Sendspin音频播放和人脸追踪平滑

fix: 修复人脸追踪偏上问题

debug: 添加最终pose日志

debug: 暂时禁用face tracking smoothing进行调试

fix: 反转pitch方向，修复机器人向上看的问题

debug: 添加人脸追踪调试日志，移除Y偏移，增加smoothing factor

fix: Noise suppression启动时设置为15% (PP_MIN_NS=0.85)

fix: Noise suppression默认值改为15%

fix: 人脸追踪Y轴偏移补偿，看向眼睛而非脸部中心

fix: Sendspin PLAYER角色需要player_support参数

fix: Sendspin使用固定client_id和PLAYER角色，恢复原版人脸追踪参数

fix: 人脸追踪添加平滑过渡，避免抽搐式转头

fix: 人脸追踪Y轴偏移补偿，移除Sendspin发送逻辑

feat: Sendspin自动发现，无需用户配置

fix: IDLE state should be completely still, restore face tracking fps

fix: reduce control loop frequency to prevent daemon crash in IDLE state

feat: add Sendspin multi-room audio support (Phase 13)
