/**
 * 存量修复脚本（幂等）：把纯款号商品名（如 `PLTK016`）按主链接 SDS 分类名
 * 补成「描述名 款号」（如 `童装纯色插肩短袖T恤 PLTK016`）。
 *
 * 运行：
 *   pnpm --filter @inkreach/api fix:good-names             # dry-run，只打印清单
 *   pnpm --filter @inkreach/api fix:good-names -- --apply  # 实际写库
 * origin_goods.good_name 为 SDS 纯镜像（每小时同步覆盖），本脚本只改 goods.good_name。
