Incorrect types for MediaFeature

MediaFeature type is missing WithChildren

File: dist/node-types-mntWKkN-.d.ts

Problem

MediaFeature can have children beyond the .value node at runtime, but the type does not extend WithChildren. This makes node.has_children and for (const child of node) TypeScript errors even though they work correctly.

A concrete example is the CSS hack min-width:0\0. The parser emits a MediaFeature with two children: a Number node (0) exposed via .value, and a sibling Identifier node (\0) only reachable by iterating children.

Current definition

type MediaFeature = CSSNode & {
  readonly type: typeof MEDIA_FEATURE;
  readonly type_name: 'Feature';
  readonly property: string;
  readonly value: CSSNode | null;
  clone(options?: CloneOptions): ToPlain<MediaFeature>;
};

Expected definition

type MediaFeature = CSSNode & WithChildren<Identifier | Number | Dimension> & {
  readonly type: typeof MEDIA_FEATURE;
  readonly type_name: 'Feature';
  readonly property: string;
  readonly value: Identifier | Number | Dimension | null;
  clone(options?: CloneOptions): ToPlain<MediaFeature>;
};

Changes

1. Add WithChildren<Identifier | Number | Dimension> — boolean features have no children; plain features have one child matching the value; the 0\0 hack produces two children.
2. Narrow value: CSSNode | null → value: Identifier | Number | Dimension | null to match the actual child union.

Start with the MediaFeature definition in dist/node-types-mntWKkN-.d.ts and compare its child-related types with the runtime behavior described for min-width:0\0. The work is done when MediaFeature exposes the specified WithChildren union and its value property is narrowed to Identifier, Number, Dimension, or null.
