/**
 * Unwrap a parsed Hson container shape (`_hson_root` → `_hson_elem`) into its concrete child nodes.
 *
 * This normalizes inputs that may be wrapped by the parser (or produced by transforms)
 * so downstream mutators can operate on “real” nodes rather than structural wrappers.
 *
 * Behavior:
 * - If a node is `_hson_root` whose first child is an `_hson_elem`, returns the `_hson_elem`’s child nodes.
 * - Otherwise, returns the node wrapped in a single-item array.
 * - Always returns an array.
 *
 * @param content - A single node or list of nodes that may include `_hson_root`/`_hson_elem` wrappers.
 * @returns The unwrapped concrete child nodes (stripped of `_hson_root`/`_hson_elem` wrapper nodes).
