refactor(agui): remove health check endpoint and update tests

The health check endpoint was removed from the AGUI protocol handler
as it's no longer needed. All related test cases have been updated
to reflect the new health check location at the root path.

BREAKING CHANGE: The /ag-ui/agent/health endpoint has been removed
and health checks are now available at /health

移除 AGUI 协议的健康检查端点并更新测试

AGUI 协议处理器中的健康检查端点已被移除，
因为它不再需要。所有相关测试用例都已更新以反映
新健康检查位置在根路径。

重大变更：/ag-ui/agent/health 端点已被移除，
健康检查现在可在 /health 路径获取
