 * @brief Test NotificationModule alert processing

 * Workflow:
 * 1. Publish scheduler:hyperfocus_alert (triggers notification)
 * 2. Verify NotificationModule processes it (logs will show notification)
 * 3. Validate notification system responds correctly
 *
 * Note: NotificationModule doesn't publish responses, it processes
 * alerts and shows them. This test validates the module accepts
 * and processes the alert without errors.
