feat: 清理 control_node + 引入 task 一等公民

- control_node 标注 DEPRECATED：保留目录壳子供未来远程探针节点复用，删除调用路径与相关测试
- 新增 task 表：极简元数据持久化 regulatory_node 完成的短任务（出报告/写文件/查询整理）
- regulatory_node 自标注：MessageResponse 扩展 task_action/title/summary，_run 末尾非阻塞落库
- query_task_list 改查 task 表，符合用户对"任务列表"的直觉，与 workflow 体系解耦
- 新增 /api/v1/task/list|/{id} 只读 API（task 由 regulatory 内部触发，不开放对外创建）
