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.
Fixes WPT crash:

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.
The introduction of frames means that data is no longer tied to a specific Page
or Context. 255b9a91cc introduced Origins for
v8 values shared across frames of the same origin. The commit highlighted the
lifetime mismatched that we now have with data that can outlive 1 frame. A
specific issue with that commit was the finalizers were still Context-owned.
But like any other piece of data, that isn't right; aside from modules, nothing
should be context-owned.
This commit continues where the last left off and moves finalizers from Context
to Origin. This is done in a separate commit because it introduces significant
changes. Currently, finalizers take a *Page, but that's no longer correct. A
value created in one Page, can outlive the Page. We need another container. I
original thought to use Origin, but that isn't know to CDP/MCP. Instead, I
decide to enhance the Session.
Session is now the owner of the page.arena, the page.factory and the
page.arena_pool. Finalizers are given a *Session which they can use to release
their arena.
