+DBHub 风格 SQL 执行与元数据探索。
+
+**实现单一来源**：``backend/db/dbhub_tools.py``（含 ``execute_sql`` / ``execute_sql_all`` /
+``execute_sql_count_only`` / ``search_objects`` / ``probe_sql_execution_status`` / ``probe_sql_execution_status_ex``）。
+
+本文件将 ``backend`` 加入 ``sys.path`` 后从 ``db`` 包转发，避免 ``tools/`` 与 ``backend/db`` 双份漂移。
+若你在本仓库内迭代 DB 工具逻辑，请直接修改 ``backend/db/dbhub_tools.py``。
