- Replace bbox crop with YOLOv8-seg person segmentation
- Full-frame green screen: only person silhouette kept
- Top 5 preview images per actor by mask area (IMAGE output)
- Accurate time segmentation: only frames where person is visible
- No green gaps between segments
- Add seg_model_path parameter
- Rewrote __init__.py to use importlib for loading modules
- Avoids conflict between plugin's nodes/ dir and ComfyUI's nodes.py

- Successfully detected 10 actors with green screen output
- actor_1 correctly shows 2 segments (appeared mid-video, left, returned)
- All actor_info.json and per-actor MP4s generated correctly
