feat(录音): 容器接 Web触摸观察(方案A onTouch)+录音浮层+SHOW_RECORDING+计时/上滑取消/太短决策

- 补 import: AudioEvents, ShowRecordingRequest, RecordResult (from common) + RecordingOverlay
- 新增字段: recordOverlayVisible/recordState/recordResultEvent/touchDown/touchStartY/
  recordingActive/wantCancel/recordSeconds/recordTimer
- subscribeEvents() 追加 SHOW_RECORDING → onShowRecording
- onShowRecording: 手指未按时立即 cancel 回投; 否则显浮层+启计时器
- onWebTouch(TouchEvent): Down记起点/Move判上滑(>100vp)/Up调 finishRecording
- finishRecording: <0.8s→tooShort延1.3s撤层; 上滑→cancel; 否则→send; 一次性清 resultEvent
- 大厅/子游戏 Web 各加 .onTouch((e)=>this.onWebTouch(e)) (方案A, 不消费触摸)
- Stack 顶层(ShareGuideDialog 之后)追加 RecordingOverlay({ state })
- aboutToDisappear 清 recordTimer

对应 §10 录音浮层设计; 手势观察接线
