TimeoutError returns ChatResponse(success=False, error="timed out"). - chat_service.py: generic except block no longer exposes str(exc) to the caller; logs the full traceback internally and returns a safe message. - test_local.py: test_chat now asserts HTTP 200 (always true) and checks success flag for semantic result; non-200 guard removed as dead code.
