+### Fixed
+- **Force-quit mic release**: on termination the host app now synchronously stops `AVAudioEngine`, deactivates `AVAudioSession`, and ends Live Activities (Dynamic Island + Lock Screen) in `applicationWillTerminate`, reducing “microphone in use” errors after reopening. / **强杀麦克风释放**：进程终止时在 `applicationWillTerminate` 内同步停止 `AVAudioEngine`、释放 `AVAudioSession` 并结束 Live Activity（灵动岛 + 锁屏），降低强杀后重开提示麦克风被占用的概率。
