Nick Payne 85975d6cc3 optimise hot-path audio pipeline: zero-copy ring buffer, pre-allocated converter buffers
- Replace Swift Array<UInt8> ring buffer with UnsafeMutableRawPointer to
  eliminate COW ref-count checks on every write/read
- Add append(from:count:) to copy directly from Core Audio buffer pointer
  into the ring buffer, removing the per-callback Data heap allocation
- Pre-allocate AVAudioPCMBuffer pair in AudioFormatConverter and reuse
  across transform() calls (lazy init, capacity-checked)
- Fix float-to-int truncation in output frame count calculation (ceil)
- Add comprehensive AudioBuffer test suite (12 tests) including proper
  wrap-around coverage for both append and read paths
