ListView
Defined in: ui/collection/list-view.ts:73
Virtualized list driver. Owns a ViewPool + DataSource subscription;
on each update() computes the visible index range and syncs the
mounted item set to match.
Does not own input — callers drive scrolling by calling
setScrollOffset(). Typical wiring: a ScrollContainer primitive (or
the app’s input layer) computes a new offset and pushes it in.
