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.
