isaac ab68a1af82 InstantPage V2: render collage & slideshow blocks ... Port V1's collage and slideshow InstantPage blocks into the V2 renderer (previously grey-box placeholders). - Collage: layoutCollage computes the mosaic (MosaicLayout, the grouped-message engine) over inner image/video sizes and flattens it into existing top-level .mediaImage/.mediaVideo items + a caption, so gallery / reveal-cost / registry / hidden-media all handle the cells with no collage-specific code. Right-edge cells bleed 4pt for the bubble's rounded clip. - Slideshow: a new .slideshow laid-out item + InstantPageV2SlideshowView, an eager paged carousel (UIScrollView + PageControlNode) of InstantPageImageNode pages, wired through frame/offsetBy/collectMedias/stableId/reuse/makeItemView and the reveal-cost non-text list. - Gallery transitions generalized onto InstantPageItemView via instantPageTransitionNode(for:)/instantPageUpdateHiddenMedia(_:) (default nil/no-op; explicit per-class witnesses on the 4 static media views, the slideshow forwards to its live pages) so the multi-media slideshow can participate alongside single-media views.
