 * INTEGRATION TESTS - Simplified
 *
 * These tests focus on synchronous methods only, avoiding the complex async streaming
 * functionality that caused memory issues. Tests the actual integration between ChatService
 * and its dependencies.
 *
 * Note: The complex submit() method with async generators is better tested through E2E tests.
