 * Citami Connector — uninstall.
 *
 * WordPress runs this file when the plugin is DELETED from Plugins (not on
 * deactivation). Removes every option, transient and cron event the plugin
 * created. Content the customer keeps on purpose is left alone: the FAQ
 * page we created stays (it is real content), llms.txt stays (it may have
 * a manual part). Head blocks disappear with the options, so nothing of
 * ours is printed anymore.
