 * Uninstall script for AI Snippet SEO Pro

 * - The main plugin option.
 * - ONLY the plugin’s own score meta key (`_aissp_score`) from posts and terms.
 *
 * What this keeps (intentionally):
 * - User content metas:
 *     - `_aissp_focus_keyword`
 *     - `_aissp_seo_title`
 *     - `_aissp_seo_description`
