test: full pipeline test passed

- YOLOv8 model downloaded successfully (6.5MB)
- Tested with sample_demo_1.mp4 (640x360, 25fps, 9.7s)
- Detected 1 actor (actor_0)
- Output: actor_0.mp4 (497KB, green screen cropped)
- Output: actor_info.json (valid JSON with frame ranges)
- Node loads correctly in ComfyUI environment
- Symlink to custom_nodes verified
