### Added

- Added `pause_frame_processing` parameter to `CartesiaTTSService` to allow
disabling frame processing pausing during TTS generation.

- Added `wait_for_all` argument to the base `LLMService`. When enabled, this
ensures all function calls complete before returning results to the LLM (i.e.,
before running a new inference with those results).

I don't think we want to add a constructor argument, we simply want to set this to False.
