Cherokee 322f8d9b71 improve: performance optimization — downscale inference, defer green screen, add skip_every_n ...

- Optimization 1: Downscale frames to 640px max-side before YOLOv8-seg
  inference in segmenter.py, resize masks back to original resolution
  (~13% speedup from reduced post-processing)
- Optimization 2: Store bool masks instead of composited BGR frames in
  MaskActor.frames (~97% memory reduction per tracked frame, from ~6MB
  to ~200KB per entry). Green screen now applied on-the-fly during
  encoding rather than during tracking.
- Optimization 3: Add skip_every_n parameter to VideoActorExtractor
  (default 1=all, 2=every other frame, up to 30). Users can trade
  precision for speed.
- Add per-substep timing (Detection vs Tracking) printed after frame loop
