 * Hook that runs **synchronously** when the Milkdown editor's container mounts.

 * Returns a callback ref to attach to the container div. Unlike a useEffect-based
 * approach, this runs during the React commit phase — before any async effects or
 * scheduled callbacks — so the dispatch wrapper is in place before collab can fire.
 *
 * Responsibilities:
 * 1. Exposes ProseMirror view on DOM element (for testing)
 * 2. Provides replaceContent function (for revision restore)
 * 3. Tracks headings and fires onHeadingsChange callback (for TOC)
 * 4. When collab: registers post-dispatch via postDispatchRef (single wrapper in EditorCore).
 *    When no collab: wraps view.dispatch to track heading changes and guard teardown races.
