 * Asset Loader Utility Class
 *
 * Provides static methods to enqueue scripts and styles with WordPress.
 * Automatically handles .asset.php metadata files generated by build tools like wp-scripts.
 * Falls back to file modification time for versioning if asset metadata is not available.
 *
 * Usage:
 *     AssetLoader::enqueue_script( 'my-handle', 'my-script' );
 *     AssetLoader::enqueue_style( 'my-style', 'my-stylesheet' );
