 * matchMedia mock for testing

 *
 * @example
 * ```typescript
 * // Setup mock
 * setupMatchMediaMock();
 *
 * // Test dark mode detection
 * setMediaQueryMatch('(prefers-color-scheme: dark)', true);
 *
 * const darkMode = window.matchMedia('(prefers-color-scheme: dark)');
 * expect(darkMode.matches).toBe(true);
 * ```
