Describe the bug

When integrating with agentscope-studio in a web service, after the request ends, the observed request in agentscope-studio remains in the running state.

Unless I terminate the entire web service, but this is clearly not feasible just because of a single request.

To Reproduce
Steps to reproduce the behavior:

1. You code

@GetMapping("demo")
    public SseEmitter demo(String userMessage) {
        SseEmitter sseEmitter = new SseEmitter(-1L);
        // 初始化studio
        StudioManager.init()
                .studioUrl("http://localhost:3000")
                .project("testAgent")
                .runName("testAgent" + System.currentTimeMillis())
                .initialize()
                .block();
        DashScopeChatModel model = DashScopeChatModel.builder()
                .apiKey("sk-xxxxxxx")
                .modelName("qwen3-max")
                .build();

        ReActAgent reActAgent = ReActAgent.builder().name("AI助手").sysPrompt("你是一个乐于助人的AI助手")
                .model(model).hooks(List.of(new StudioMessageHook(StudioManager.getClient())))
                .build();
        Flux<Event> stream = reActAgent.stream(Msg.builder().role(MsgRole.USER).textContent(userMessage).build());
        stream.subscribe(msg -> {
                    try {
                        sseEmitter.send(msg);
                    } catch (IOException e) {
                        throw new RuntimeException(e);
                    }
                }, e -> {
                    log.error("error", e);
                }, () -> {
                    sseEmitter.complete();
                    StudioManager.getClient().shutdown();
                }
        );
        return sseEmitter;


    }

当在web服务中使用agentscope-studio的时候，当请求结束的时候，在agentscope-studio的页面中，看本次请求一直是running的状态，除非我终止整个web服务的时候，才会变成done的状态
