MagMueller 5ec5c8d43a perf: hoist CDP session lookup + cap paint order rect explosion ...

Two additional performance fixes for heavy pages:

1. Hoist get_or_create_cdp_session() outside _construct_enhanced_node
   Previously called once PER DOM NODE inside the recursive tree
   construction. On a 100k-element page, this was 100k+ async
   operations. Now resolved once before recursion starts.

2. Add _MAX_RECTS=5000 safety cap to RectUnionPure
   The paint order rect union can fragment exponentially with many
   overlapping translucent layers (each add() splits up to 4 rects).
   Cap prevents memory/CPU explosion on complex pages.

Also: expanded stress test suite to 15 pages (up to 132k elements)
including shadow DOM + iframe combos, overlapping layers, cross-origin
iframes, and a 100k flat element test. All 15 pass.
