     * Converts an object to a JSON-serializable format with comprehensive type handling and circular reference protection.
     *
     * Handles special cases including:
     * - Date objects (converted to ISO strings)
     * - RegExp objects (converted to string representation)
     * - Error objects (converted to structured object with name, message, stack)
     * - Node.js-specific objects (Timeout, EventEmitter, etc. - converted to descriptive strings)
     * - Circular references (replaced with '[Circular Reference]' string)
     * - Functions and symbols (excluded from output)
     *
     * @param object - The object to convert to JSON-safe format
     * @returns A JSON-serializable version of the input object, or the original value for primitives
     *
     * @example
     * ```typescript
     * const complexObj = {
     *   date: new Date(),
     *   error: new Error('test'),
     *   regex: /test/g,
     *   func: () => {},  // Will be excluded
     *   circular: null as any
     * };
     * complexObj.circular = complexObj;  // Create circular reference
     *
     * const safe = JsonUtils.objectToJson(complexObj);
     * // Result: { date: "2023-...", error: {...}, regex: "/test/g", circular: "[Circular Reference]" }
     * ```
