vangel76andClaude Opus 5.5 50ce8b090c #805: Morph Cut morphs along optical flow instead of cross-dissolving ...

Problem: Morph Cut rendered as a plain Cross Dissolve, so a jump cut in a
talking-head shot showed the subject twice at half opacity during the
transition, and the GPU plan mixed it as a dissolve too.

Fix: Morph Cut warps both frames along the dense optical flow between them
(the Lucas-Kanade flow of #780, crates/render/src/flow.rs) and blends, so the
subject moves from its place in the outgoing shot to its place in the incoming
one; where the frames do not correspond it stays the cross dissolve. Frames
inside a Morph Cut are planned whole on the CPU (no longer a GPU-mixable
"simple" transition) and cost as a complex transition in the preview estimate.
Morph Cut goldens re-blessed. No face tracking yet.
