- Use YOLO to detect armor ROI regions instead of full image
- Expand ROI by configurable pixels (default 75) for light detection
- Apply traditional binary + light detection within ROI
- Keep YOLO's number classification result
- Use LightCornerCorrector for corner refinement
- Add debug visualization for ROI regions (blue rectangles)
- Compatible input/output with armor_detector node
