isaac 0d5b051820 InstantPage V2: support nested <details> blocks ... A details block nested inside another rendered (title + chevron) but could not expand: its body is hosted by a fresh InstantPageV2View whose detailsTapped closure was never wired (only the top-level view's is, by the bubble), so the nested title's tap hit a nil closure and was dropped. Wire the body view's detailsTapped to chain through this view's onTitleTapped, which makeItemView already routes to the owning view's detailsTapped -> the bubble's toggle handler; this chains up through arbitrary nesting depth. Also make the bubble's defaultExpanded(forDetailsIndex:) recurse into expanded bodies so a nested details whose model default is expanded toggles from the correct state (the flat top-level scan missed nested indices). Known pre-existing limitation (unchanged): V2 keys expansion state by a flat DFS index, so expanding a nested details can shift sibling indices.
