/**
 * Permanent aliases for legacy unversioned and folded v2 WCPOS REST API class names.
 *
 * WCPOS Pro and third-party extensions subclass these controllers by FQCN.
 * Keep the old names as a permanent public API while implementations live in V1.
 *
 * Loaded via Composer's `files` autoload (so bundled consumers like WCPOS Pro,
 * which load this package through vendor/autoload.php and never execute
 * woocommerce-pos.php, still get the aliases) AND required directly from the
 * plugin bootstrap. The guard makes double-loading a no-op.
 *
