Build a hit-test display list while recording paint output. Use it as source of truth for point hit testing instead of recursively walking the paintable tree in reverse paint order. The retained list records target paintables, visual context indices, border radii, caret rects, and line metadata needed by hit testing. It also keeps a spatial index so point queries inspect nearby items before checking containment in paint order. Refresh scroll state before hit testing so visual context transforms use current scroll offsets. Add text tests for rounded hit regions and selection across non-text content.
