Auto-match each named July frame by film+actor+class and re-extract it from
the current learned-boundary flood replay, drawing GT-aware boxes: green TP,
red FP, orange unknown, plus the blue off-screen/missed (X-Ray cast, no face)
FN panel. Adds rematch_frames.py, the tool that does the matching.
Zooey Deschanel is dropped: the current pipeline no longer makes that
false identification, so the frame is removed and the July deep-dive notes
the fix rather than showing a stale error.
