Datamosh: torn horizontal strips, chroma shift and scan noise drag the first shot into the next

## Prompt that renders it frame-exact

Add the "StripDatamoshGlitch" transition from GL Transitions (by bread, MIT; https://gl-transitions.com/editor/StripDatamoshGlitch, GLSL source https://github.com/gl-transitions/gl-transitions/blob/master/transitions/StripDatamoshGlitch.glsl) on a hard beat in a music or gaming edit: 0.6 s, linear progress. It is busy on purpose; keep it short. Remotion: `npm install gl-transitions @gl-transitions/remotion @remotion/transitions`, then a `<TransitionSeries.Transition>` with `presentation={glTransition({ name: "StripDatamoshGlitch", params: { strength: 1.0, chroma: 0.032, tear: 0.18 } })}` and `timing={linearTiming({ durationInFrames: 18 })}` (18 frames at 30 fps). HyperFrames: draw the GLSL on a full-frame WebGL canvas over the cut, with the outgoing and incoming frames as the from/to textures, and compute progress from the composition time, clamp((t − cutStart) / 0.6, 0, 1); never from requestAnimationFrame or a timer, so every frame renders the same. ffmpeg's xfade can't run GLSL. Of its nine uniforms the useful ones are `strength` (1.0), `horizontalBars` (42) and `verticalSlits` (18) for strip density, `chroma` (0.032) for the RGB split, `tear` (0.18) and `flashAmount` (0.2).
