Detailed Description

Lays out the UI hierarchy, builds the frame's 2D draw list, and routes pointer interaction.

Runs in the Transform stage, after BehaviorSystem writes UI components and before RenderSystem draws the ctx.ui it publishes. Reads no WorldTransform. Canvases walk in ascending sortOrder; a clip rect descends with the walk and bounds both drawing and the pointer.
