/**
 * Idempotent patch — "catalog" view for the Tools tab.
 *
 * Any tool that belongs to a guarded integration batch (WPBakery, WooCommerce,
 * Yoast, Wordfence, LiteSpeed, WP Rocket, WPML, Elementor, ...) whose plugin is
 * NOT installed/active on this site is normally inert and absent from the Tools
 * tab. This patch makes those tools visible anyway — rendered LOCKED, grouped by
 * the plugin that provides them, with an "install & activate it" note — so the
 * admin can see the full catalog and knows exactly what to install.
 *
 * The catalog is derived at runtime from the Batch*.php sources (guard symbol +
 * $def('name','desc') pairs), so it stays correct automatically as new guarded
 * families are added. Nothing here touches the live enable/disable logic or the
 * "X of Y tools enabled" counts — locked tools aren't real tools on this site.
 *
 * Usage:  php patch-tool-catalog.php [ABS_PATH_TO/includes]
 * Safe to run repeatedly.
