refactor(audio): Finalize audio sync, update docs, and clean up test artifacts

- Implemented sample-accurate audio-visual synchronization by using the hardware audio clock as the master time source.
- Ensured tracker updates and visual rendering are slaved to the stable audio clock.
- Corrected  to accept and use delta time for sample-accurate event scheduling.
- Updated all relevant tests (, , , , ) to use the new delta time parameter.
- Added  function.
- Marked Task #71 as completed in .
- Updated  to reflect the audio system's current status.
- Created a handoff document: .
- Removed temporary peak log files (, ).
