背景：
后端使用agentscope-java2.0基于权限系统开启了工具二次确认功能，合并fix(agui): emit AG-UI interrupt for permission-type HITL tool confirmation (#2437) (#2495 分支兼容了agui，并基于postman验证agui方式的后端返回ask询问、工具恢复执行环节均正常。
问题现象：
1、通过postman测试和前端F12均可以正常接收到后端返回的RAW和RUN_FINISHED事件。
2、但是前端基于@ag-ui/client的agent.subscribe方法无法监听到RAW和RUN_FINISHED事件，感觉是被拦截或过滤掉了。
agui后端返回的ask询问事件流如下：
