+SQLite 没有原生表/字段 COMMENT，宿主「数据管理」页面靠这两张元数据表
+拿到中文表名/列名/可编辑性等。字段顺序由 ``CREATE TABLE`` + ``PRAGMA table_info``
+的 ``cid`` 决定，不读 ``display_order``。

+本文件是模板 ``scripts/db/display_metadata.py`` 的最小可用子集：
+- ``init_display_metadata_tables``：建元数据表
+- ``upsert_table_metadata`` / ``upsert_column_metadata``：写入展示元数据
+- ``list_physical_column_names``：按 cid 列出物理字段名
