Updates `Element.checkVisibility` to iterate through document
stylesheets and check for matching rules with `display: none`.
Also ensures `<style>` elements register their sheets and
initializes them immediately upon addition to the DOM.
Refactors `CSSRule` to a union type for better type safety and updates
`CSSStyleRule` to use `CSSStyleProperties`. Adds comprehensive tests for
`insertRule`, `deleteRule`, and `replaceSync`.
Adds a CSS rule parser and implements `insertRule`, `deleteRule`, and
`replaceSync` in `CSSStyleSheet`. Also updates `CSSRuleList` to use
dynamic storage and populates sheets from `<style>` elements.
Next.js hydration references FileList as a global for feature detection.
Register a minimal stub (length=0, item()→null) so the type exists in
the global scope and the reference check doesn't throw.
Custom element callbacks aren't allowed to call document.open/close/write while
parsing.

On BSD, a listening socket isn't considered connected, so this error is
expected. Maybe we shouldn't call shutdown at all, but I guess it's safer this
way.
The bridge.finalizer resolves Page through its own module graph, which
can differ from Range.zig's import in release builds. Store a pointer
to the live_ranges list directly on AbstractRange so deinit can remove
without accessing Page fields.
Add a weak finalizer to Range that removes its linked list node from
Page._live_ranges when V8 garbage-collects the JS Range object. This
prevents the list from growing unboundedly and avoids iterating over
stale entries during mutation updates.
Move the per-range update logic from Page into AbstractRange methods
(updateForCharacterDataReplace, updateForSplitText, updateForNodeInsertion,
updateForNodeRemoval). Page now just iterates the list and delegates.
Remove redundant start_container == end_container check in insertNode —
collapsed already implies same container.
When calculating accessible names for elements without explicit labels, multiple descendant text nodes were previously concatenated directly together. This adds a space between distinct text node contents to prevent words from sticking together.
Previously, semantic_tree_text hardcoded prune = false, which bypassed the structural node filters and allowed empty none nodes to pollute the root of the text dump.
This prevents token bloat in JSON/text dumps and ensures that StaticText leaf nodes are not incorrectly pruned when structural containers (like none, table) hoist their text.
This fixes a bug where only the first text node was being returned, causing fragmented text nodes (e.g. <span>Sub</span><span>mit</span>) to be missing their trailing text.
