fix(audio): prevent app hang when audio device doesn't respond to cleanup

[tomchapin]

Summary

• Fixes app freeze when stopping recordings with USB/wireless audio devices (e.g., Astro A50)
• Some audio devices can hang indefinitely during stream cleanup on Windows WASAPI
• App now gracefully recovers instead of freezing

Changes

• Wrap drop(stream) in a separate thread with 1-second timeout
• If timeout fires, abandon the hung thread and continue gracefully
• Enhanced error callback to trigger stop on device errors (e.g., disconnection)
• Added detailed logging for debugging audio device issues

Test plan

• Tested with Astro A50 headset in frozen state
• Verified app recovers after 1-second timeout
• Verified recording pill disappears properly
• Verified "no audio recorded" feedback shows
• Verified user can immediately start new recording
• Verified normal operation works when device is healthy

Log output when timeout fires
