 * @brief Demonstrates parsing, writing, and reloading JSON with Vix.cpp helpers.
 * This example shows how to:
 * - Parse a JSON string with `loads()`.
 * - Write it safely to disk using `dump_file()` (atomic operation).
 * - Reload the same file using `load_file()`.
 * - Print the formatted JSON using `dumps()`.
 * The `dump_file()` function writes to a temporary file (with `.tmp` suffix)
 * before renaming it atomically to prevent corruption — making it suitable
 * for configuration storage, caching, or transactional file operations.
 * ### Example Output
 *   "a": 1,
 *   "b": [
