/**
 * Uninstall {{PLUGIN_NAME}}.

 * This file runs when the plugin is deleted from the WordPress admin.
 * Add any cleanup logic here — for example, removing options or custom tables.
 *
 * By default this starter does NOT delete any data.
 * Uncomment and extend the sections below only when your plugin stores data
 * and you are confident that removal is the right behaviour.
