vangel76andClaude Opus 5.5 e56ddd0e36 #780: Optical Flow time interpolation synthesises motion-compensated frames ...

Problem: a speed-changed clip set to Time Interpolation > Optical Flow
rendered exactly like Frame Blending, a cross-fade of the two neighbouring
source frames, so moving objects showed double images.

Fix: new filmcraft_render::flow. It computes dense coarse-to-fine
Lucas-Kanade flow both ways on a luma pyramid at most 640 px wide, drops
motion wherever standing still explains the window as well (flicker on
static content), forward-splats both flows to the in-between time
(Baker et al. 2011), and warps both frames there. Each fetch is weighted
by how well its own flow agrees, so uncovered background comes from the
frame that shows it. Pixels that look the same in both frames, or where
neither fetch agrees, fade to the plain cross-fade. media_image uses it
for OpticalFlow clips. docs/gaps.md G18 and target-app-parity updated
(also drops the #415 / #458 items, already fixed on main).
