admin c70d5d860e feat(cluster): 集群化落地 —— Manager/Worker 拆分 + 归属租约 + 跨机验证(T08)
背景:把平台从「单机单进程」改造成「1 组 Manager + N 台 Worker + 共享归属状态」,
硬约束 = 全程兼容单例模式(deployMode 默认 local;生产切换前 47 一行未动)。

主要改动
1) 数据模型 v7(SQLite 与 PG 两方言同步):新增 dsh_hosts 注册表 +
   dsh_instances.{host_id,epoch,heartbeat_at,lease_until};claimInstance 原子抢占
   (UPDATE … WHERE host_id IS NULL OR lease_until < now)+ pinInstanceHost 钉住归属。
2) 租约与 fencing:src/supervisor/lease.ts(acquire/renew/release + stillHolder 判据 +
   ttl > 2×renew 硬校验);心跳里续租,失权即向 worker 下发更高 epoch(self-fencing)。
   ⚠️ release 只清租约(lease_until),**保留 host_id** —— host_id 是「用户数据在哪台」的锚点。
3) Worker agent(src/worker/agent.ts,子命令 dshs worker):实例生命周期 + 文件面 /fs/*
   + 幂等键(operationId)+ 鉴权(timingSafeEqual);Worker 不写控制面数据
   (apiKey/uid 由 Manager 随 launch 投递,R5 收窄)。
4) 远端 Spawner + LeasedSpawner:按 host 路由(**粘性优先**:有历史归属且那台 up 就留在原地,
   否则按容量选最空的)+ 容量准入 + deployMode=cluster 装配(systemd drop-in,可回滚)。
5) bwrap 修正:**所有挂载点的中间目录统一前置 + 去重 + 由外到内**(「就近创建」会在嵌套前缀下
   遮掉已绑挂载点 ⇒ bwrap: Can't chdir);且**只能用 --tmpfs**,用 --perms 会让 47 的
   bwrap 0.4.0 直接拒启动(沙箱全挂)。
6) 跨机隧道 src/worker/tunnel.ts:SSH ControlMaster + 动态 -R 转发;**自愈由 agent 本地
   20s 定时器驱动**(不能只放 /healthz —— 心跳本身经隧道进来,断了就没人触发它)。
7) 文件面按归属路由(RemoteUserFs):实例与文件必须落在同一台机器,否则实例看不到自己的文件。
8) 观测面:dshs doctor / dshs cluster status。

验证(本次均已实跑)
- test/lease.test.mjs:SQLite 10/10 == PG 10/10
- 组件级端到端 5 个:verify-cluster-{agent,lease,fs,migrate,live}.mjs
- 真跨机(47 Manager / 106 Worker,跨云 + 反向隧道)verify-cluster-cross.mjs 九步全绿
- 域名形态访问 verify-cluster-domain.mjs(<user>.域名 → Manager → 远端实例;越权 403)
- 冒烟 scripts/smoke-*:6/8,失败项与改动前基线完全相同(无回归)
- 生产切换与回滚剧本见 dsh-server-docs/交接单/T08-集群化落地-兼容单例模式.md §16
