查找租户的虚拟根节点（virtual_root_node_xxx）。 触发场景：创建任务时需要指定上游依赖为"根节点" / 遇到 NodeWithoutUpstream 报错 / 新任务 UpStreamList 为空需要挂默认上游 / 需要获取项目 DagId。 方法：读任意已有任务的 TaskInfo.DagId → 去掉 d_ 前缀 → 拼出 virtual_root_node_数字。 注意：后缀不是 project_id 也不是 tenant_id，是项目 DagId 的数字部分。 触发词：根节点、虚拟根节点、virtual_root_node、上游依赖、NodeWithoutUpstream、UpStreamList 为空、DagId、默认上游。
