AdoptedStyleSheets.cpp still handled CSS-side fallout from adopted sheet list mutations directly. Move sheet attachment and media-query setup to a CSS invalidation helper, along with rule-cache invalidation. The observable array callbacks continue to validate JS values and same-document construction rules. The helper now owns the CSS work for when a constructed stylesheet becomes visible to, or is removed from, a Document or ShadowRoot.
