 * Registers a schema `enum` — a closed set of string values a field may hold.

 * @returns {{kind: 'enum', values: string[], includes: function(unknown): boolean}}
 *   The registered entry, used by validateValue() to check a ref'd value's
 *   membership; also returned so a generator can build a discoverable constant from it.
