6	* Cleanup policy:
7	*
8	* - Credentials (the Google Indexing service account — a plaintext private
9	* key — and the IndexNow API key) are ALWAYS deleted. They must never be
10	* left behind in wp_options by a plugin that is no longer installed.
11	* - Everything else (custom tables, options, transients, per-post SEO meta,
12	* log files) is only removed when the site owner opted in via the
13	* "Delete all plugin data when the plugin is uninstalled" toggle in
14	* Advanced Settings. The default is OFF, per WordPress uninstall guidelines.
15	*
16	* The opt-in option is read BEFORE any options are deleted, because the
17	* option itself is plugin data.
18	*
19	* For multisite, the cleanup runs once per site when the plugin is
20	* network-activated and removed.
21	*
