/**
 * Charitable Connect callback endpoint.
 *
 * Called by upgrade.wpcharitable.com to activate or install Pro. This file
 * loads WordPress and defines CHARITABLE_CONNECT_CALLBACK so the main plugin
 * can run the actual callback on init at priority -9999, before any redirect
 * (e.g. to login) runs. That way the upgrade server's request (no cookies)
 * still gets JSON instead of the login page.
 *
 * @package Charitable
 * @since 1.8.9.6
