feat(voice): 桌面端 JARVIS 语音坞——麦克风上行 + TTS 播放队列(Phase 1 收口)

右下角悬浮麦克风：点按说话→转写→提交任务→跳运行页→朗读回答，接入既有运行·观测流。

- lib/voice.ts: VoiceClient——一条 WS 承载上行 PCM16k/下行转写/下行 TTS PCM24k；
  ScriptProcessorNode 采麦(48k→16k 降采样+Float32→Int16)；AudioBufferSourceNode
  排队调度做无缝连续朗读；start/end/barge_in/bye 控制；ready/transcript/task/speaking/tts_end
- shell/VoiceDock.tsx: 悬浮麦克风 UI(聆听/思考/朗读态 + 转写气泡 + 打断)，懒建客户端(用户手势启 AudioContext)
- App.tsx: onVoiceTask 把语音 task 挂回 attachRun(后端已提交,前端只 attach)；挂载 VoiceDock

真识别/合成需部署联调(真连火山+admin录入语音配置)；本地过 tsc/build/68 测试。
