ukimsanov a85a507cdc fix(shader-transitions): page-side render dropped shader transitions and final-scene content ...

Page-side compositing (default on) silently dropped HyperShader.init shader
transitions in the engine render. The compositor clones the from/to scenes to
feed drawElementImage, but cloneNode copies the GSAP opacity-fade, and Chrome
won't paint hidden elements, so drawElementImage throws "No cached paint record"
and the shader degrades to a hard cut. Force the clones visible before capture,
as the html2canvas path already does via forceSceneVisibleInClone.

Also fixes the final scene's content dropping in the last beat: the core clip
runtime hides it shortly before the composition ends, and page-side screenshots
the live page (the layered path survives via forceVisible per-scene capture).
Un-hide the settled scene on non-transition frames.

Page-side only; retains the ~6.5x page-side speedup.
