/**
 * Uninstall routine.
 *
 * Destructive and therefore opt-in. CartShift ships no UI toggle for this on purpose:
 * the plugin's whole job is to move data you cannot afford to lose, and a "delete
 * everything" checkbox two clicks from the migration button is an accident waiting to
 * be filed as a support ticket. If you want the tables gone on uninstall, say so
 * deliberately, from somewhere you control:
 *
 *     // wp-cli
 *     wp option update cartshift_delete_data_on_uninstall yes
 *
 *     // or in a must-use plugin / theme functions.php
 *     add_filter('cartshift/delete_data_on_uninstall', '__return_true');
 *
 * Leaving it alone keeps {prefix}cartshift_id_map and {prefix}cartshift_migration_log
 * behind after deletion — the ID map is the only record of which WooCommerce row
 * became which FluentCart row, which is exactly what you want when something surfaces
 * three weeks later. Drop them by hand once you are sure.
