Performance Improvements

• CSS/Dart Engine: significantly reduce pure-Dart style application overhead for large DOM
  mounts by pruning redundant subtree restyles, optimizing selector and cascade evaluation,
  speeding pseudo-element styling, reducing declaration merge/flush work, and caching parse-time
  CSS values before resolve-time application.
• Bridge/DOM: reduce UI command package overflow during large DOM mounts.

Bug Fixes

• CSS/Backgrounds: fix mixed background-attachment: fixed, local multi-layer background
  painting, preserve authored layered background values, and warm background images early enough
  for first-paint snapshots.
• CSS/CSSOM: normalize kebab-case CSSOM property names and ensure pending inline style updates
  flush even when recomputed style matches the queued value, fixing resolved-value regressions.
• Dependencies: widen archive and intl version constraints for Flutter 3.27+ compatibility.
