CLAUDE: Tag DNN output filenames with ROI (-ROIx_y_w_h) for python flight-log analysis

The DNN save titles (-DNN-OFFSET / -HYPER-RECT / -RECT) now carry the ROI as
-ROI<x>_<y>_<w>_<h> (underscores to avoid scp/shell colon hazards) so the python
flight-log comparison can auto-restore the ROI per file instead of a hardcoded
constant - lets the real-UAS evaluation run hands-off across multiple ROIs.
