Breaking changes:

Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).

Other changes:

Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
Added cssMediaRule.matches and cssSupportsRule.matches getters.
Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
Added cssKeyframeRule.keyText getter/setter validation.
Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
Added styleSheet.ownerNode, styleSheet.href, and styleSheet.title.
Added bad port blocking per the fetch specification, preventing fetches to commonly-abused ports.
Improved Document initialization performance by lazily initializing the CSS selector engine, avoiding ~0.5 ms of overhead per Document. (@thypon)
Fixed a memory leak when stylesheets were removed from the document.
Fixed CSSStyleDeclaration modifications to properly trigger custom element reactions.
Fixed nested @media rule parsing.
Fixed CSSStyleSheet's "disallow modification" flag not being checked in all mutation methods.
Fixed XMLHttpRequest's response getter returning parsed JSON during the LOADING state instead of null.
Fixed getComputedStyle() crashing in XHTML documents when stylesheets contained at-rules such as @page or @font-face.
Fixed a potential hang in synchronous XMLHttpRequest caused by a race condition with the worker thread's idle timeout.
