 * Process contents of variables.json, in preparation for recursive substitution:
 *
 * - Strip keys ending in '#', which are treated as comments
 * - Flatten nested dicts, so {"page": {"": "A", "foo": "B"}} becomes {"page": "A", "page_foo": "B"}
 * - Add optional variants for each key, so {"page": "\\d+"} becomes {"page_optional": "(?:\\d+ ?)?"}
 * - Resolve nested references safely with circular reference detection

 *
 * Infinite loops will be detected after maxDepth iterations and the function
