feat(deploy): 裸 clone 构建改造与 en/archives 补页（T1/T4）

- build.sh：构建源改 ~/docker_apps/blog/build-repo（fetch+reset 硬跟
  origin/main，匿名 fetch）——线上=远端 main 确定性闭环，Sveltia 保存
  即自动上线生效；stamp 记录构建 commit；node_modules 留仓内做增量
  （loader 逻辑变更时须清 node_modules/.astro——EXIF 教训已注）
- en/archives/index.astro 补缺（此前 404）：PostList locale 复用 +
  译题映射；三级目录 import 深度坑再犯一次（已修）

验证: bash infra/deploy/build.sh → staging 29 html @0e792a7（裸 clone
      实测）；build 本地 28+1 页；E2E 30/30 PASS

Spec: 2026-10-25_add-blog-5c
