姚章浩 1fa35e9870 feat(release): 发布前快照硬门禁 + 云内快照 + ES/OSS 保护
按生产级备份组合落地:

- internal/releasesnapshot:新增门禁包,要求 root 下存在覆盖目标库、未过期
  (默认 24h)、含 wiki_pages.jsonl 与 sha256 的快照;本地文件再校验哈希。
  7 条单测(过期/换库/篡改/缺页/未接线/半成品)。
- 发布器:写目标库之前(Publish/Delete/Rollback 三条路)先过门禁;映射目标
  (源库→目标库,共享真实库)或 policy=always 时必须有快照;门禁未接线
  同样拒绝(fail-closed)。新错误码 release_target_snapshot_missing(不可重试)
  + 页面中文提示。6 条发布器单测。
- worker 配置新增 target_snapshot{root,max_age_hours,policy},校验 policy/
  max_age/绝对路径;compose.release-sim.yaml 只读挂载快照目录。
- scripts/target_kb_snapshot.sh:默认云内执行(与 DB 同 VPC,凭据取自 WeKnora
  容器)+ 默认不导 chunks(44s 出 8 张表);修复 \copy 不能跨行/不能带 WITH、
  ES 计数改用 knowledge_base_id.keyword。
- ES:注册 kb_backup 仓库(path.repo),首个快照 36s/4.7GB/0 分片失败,
  SLM kb-hourly(3d)+kb-daily(7d) 已建并执行成功。
- OSS:目标桶开启版本控制(此前未开启)。
- 文档 P6 增补硬门禁与云内执行;真实快照目录上门禁实测:两个绑定库通过、
  未覆盖库拒绝、未接线拒绝。

"""目标 OSS 桶的保护设置:读取状态,或开启版本控制 / 跨区域复制检查。
