 * Bundled MCP runtime (WordPress Abilities API + Parsedown).

 * shipped by another plugin — or lands in WordPress core — the newest copy
 * wins and loads once, with no fatal class collisions. This lets BetterDocs
 * serve its MCP connector out of the box, without the standalone Abilities
 * API plugin. See docs/mcp-server.md for the update procedure.
 *
 * On WordPress 7.1+, where core ships the Abilities API itself, Runtime::init()
 * stands the bundled copy down so it stops duplicating core's REST routes and
 * admin assets; on 6.4-7.0 the bundle is the only API and is left untouched.
