+// migrate_single_table 把历史草稿数据搬迁进正式表（单表发布模型的数据迁移，一次性执行）。
+//
+// 用法：
+//
+//	go run ./scripts/migrate_single_table -dry-run   # 只统计与校验，不写库
+//	go run ./scripts/migrate_single_table            # 真正搬迁
+//
+// 搬迁规则：
+//   - 正式表既有行：status 已由迁移 2026-09-22-01 置为 published，本脚本不动。
+//   - pending / rejected 草稿：插入正式表并保留原状态，草稿图片插入正式图片表。
+//   - approved 草稿：其内容当年已由「晋升」写入正式表，**不重复插入**，只丢弃元数据。
+//   - 街拍副图：parent_image_id 从「草稿图片 id」改写为「新正式图片 id」；映射缺失则降级为主图。
+//
+// 校验不通过即中止（退出码 1），且不删任何数据；删草稿表由后续迁移人工执行。
