 * Blirbit (AI Blog Writer & Autoblogger): clean-up when the plugin is deleted from the Plugins screen.
 *
 * VERSION: 1.0.1
 * UPDATES: 1.0.1: the plugin no longer uses transients; the transient clean-up stays so sites that ran 1.0.0 are left clean.
 * PRIOR (1.0.0): New. Removes the plugin's own settings (token hash, hint, Publish as user, last contact time) and any
 *          one-time token notices. Articles, images and categories Blirbit published are normal site content and
 *          are left alone.
 *
 * @package Blirbit_Connector
