[BUG] Background audio (Spotify, etc.) does not resume after voice dictation or TTS playback when CarPlay is active

What's Wrong?

When connected to CarPlay and listening to music/podcast/etc in the car, if I use voice dictation in the iOS Claude app to transcribe a message, or tapping the read-aloud button on a Claude response, background audio pauses as expected but never resumes afterward.

What Should Happen?

Claude should resume any stopped/paused audio from an external app.

(This is possible. It works with chatGPT on iOS)

Additional Information

Specific to CarPlay being active — likely an AVAudioSession interruption handling issue (app not relinquishing the audio session after use)
