 * Creates a type guard that checks if a value is an object that contains
 * at least the selected subset of properties (picked keys) from a type.
 *
 * Notes:
 * - This utility is designed to be composed with a full object type guard
 *   (e.g., from `isType`/`isSchema`). It ensures the specified keys exist.
 * - Validation of the picked properties' value types should be ensured by the
 *   provided base type guard if you call it beforehand or compose it externally.
