/**
 * Runs only when the site owner deletes this plugin in Plugins.
 *
 * Data is shared by every copy of Hermes (and by the old "Conector Blog Jurídico").
 * Nothing is removed while another copy is active, or while another copy that will
 * clean up on its own deletion (it has an uninstall.php) is still installed. Copies
 * older than 1.0.0 have no uninstall.php: they never clean up, so they do not hold
 * the data back (otherwise deleting this copy first would leave it orphaned).
 * Removed: the reads table, the plugin options (including the Google verification
 * codes), the dismissed-notice flags and the scheduled cleanup. Kept on purpose: the _blog_juridico_vistas post
 * meta (one number per post, no reader data) and the last read id, so a reinstall
 * continues the numbering (Hermes reads "id > cursor" and never accepts a repeated id).
