Handle inline stylesheet @keyframes insertions without falling back to broad owner invalidation. Recompute only elements whose computed animation-name already references the inserted keyframes name. Document-scoped insertions still walk the shadow-including tree so existing shadow trees pick up inherited animations, and shadow-root stylesheets fan out through the host root so :host combinators can refresh host-side consumers as well. Also introduce the shared ShadowRootStylesheetEffects analysis so later stylesheet mutation paths can reuse the same per-scope escape classification.
