 * Uninstall routine — runs ONLY when the plugin is deleted from the admin

 *
 * Deactivation (see the main plugin file) intentionally keeps all data so the
 * mirror survives a temporary disable. Deleting the plugin wipes everything the
 * plugin itself created:
 *
 *   REMOVED
 *     - the scheduled WP-Cron event
 *     - the plugin options (settings + last-run stats)
 *     - every mirrored post (identified by the source-id meta), including its
 *       sync meta and the featured image that was sideloaded for it
 *
 *   INTENTIONALLY KEPT (may hold unrelated content the site still needs)
 *     - local categories/tags that the sync created
 *     - WP Media Folder terms ("wpmf-category")
 *     - the site's own, non-mirrored posts and media
 *
 * On multisite the full cleanup runs for every site in the network.
