 * Table of Contents extension.
 *
 * - Backed by a real `tableOfContents` node so it survives copy/paste, undo/redo,
 *   serialisation and round-trips through HTML/JSON.
 * - Renders as a static HTML block in the document; the engine refreshes it
 *   whenever the user runs `refreshTableOfContents()` (and once on insert).
 * - Configurable via `minLevel`, `maxLevel`, `title`, `showLeader`, `showPageNumbers`.
 * - Page numbers are estimated from a rough characters-per-page heuristic until
 *   the host application supplies a real pagination map. Works well in practice
 *   because the dotted leaders absorb minor mis-alignment.
