RX-7 audio v2: turbo whistle + exhaust from the action-cam library

Browse Source

- Scanned b-action-cam-footage/clipchamp (99GB, 5 videos of the FD):
  extracted audio NAS-side via linuxserver/ffmpeg container (stream-copy),
  scanned 69min return drive per-second for engine tonality + whistle
  prominence (1.5-9kHz peak vs band median)
- New rev loop: 985-993s highway pull — 0.0Hz pitch drift over 8s,
  whistle ~1.7kHz at +33dB, exhaust + turbo captured together (seam 0.001)
- New whistle-only loop: same pull high-passed 1.2kHz — isolated spool
- SoundController: optional per-car Whistle layer that rides boost
  (throttle held at speed): fades in past 25% speed, pitch 0.9->1.35
- ROTARY_SOUND.md updated; three .ogg uploads needed in Studio now
