- #139106: \[Bug\]: Interrupting synchronous TTS can leave voice playback stuck
- PR #139112: fix(tts): do not hold an interrupted turn waiting for the sync provider

One bug report and two pull requests all concern what happens when a synchronous text-to-speech turn is interrupted, including playback possibly getting stuck. The pull request titles describe not holding the interrupted turn and abandoning in-flight synthesis, but the titles alone do not show whether these changes are merged or effective.
