 - [ ] 实现：`publishSiteContent(db,{siteKey, dryRun, confirmToken, actor})`——查询起点 `entry_locales.current_revision_id IS NOT NULL AND (published_revision_id IS NULL OR published_revision_id != current_revision_id)`（事务批量 UPDATE）；dry-run token=随机；**actor 按 --actor 传入、缺省 super_admin@cli**（前置事实 8）；P0 门禁按前置事实 8 决策不做（ADR-018 记偏离）；五列锚点共享 helper 顺手抽 `apps/api/src/modules/import/anchors.ts`（三写入器改 import——零行为变更由既有测试守护）
