feat(overlay): 覆盖网络线 序㊾ —— 探针观测面改「两台中继并集」（附 序㊽ 源码/文档补提交）

序㊾（本棒）：
- scripts/overlay-probe.cjs：OBS-01 / OBS-08 / OBS-09 的数据源由「只读 47 中继」
  改为「按两台中继取并集」，消除 worker 归属漂移时的假红 / 假 SKIP
  · endpoints 以 network:hostId:port 为键合并，online 取「或」、localPort 取在线那一侧
  · used 按 network/hostId 去重计数（不求和，避免凭空放大在册数）
  · localPort 属中继机回环落点 ⇒ 按归属分机探活（106 侧落点由 106 机上探）
  · derived（OBS-11）保持 47 视角；阈值与判据一律未放宽
  · OBS-16 计数约束：对 47 /status 的读取仍为三次、Δ 只取 47 的 counters；
    对端 106 的采样为独立一次，落在第三次采样之后，不进 (status2, status3] 门窗口
  · 新增 --peer-status-fixture（并集的对端那一半）与「并集不可取证」强制留痕
- 交接单《覆盖网络-序45-低熵块治理-测熵与实现》§16 全节（§8 前前缀逐字未变）
- 参数表 §11.16 补记（§10 现算指纹未变，值格未动）

附（前几棒已完成并已部署、但尚未入仓的源码 / 文档）：
- src/net/relay/content/*.ts、src/net/relay/index.ts、main.ts：块级寻址 C 域分离
- src/supervisor/orchestrator.ts、src/worker/agent.ts：日志采集与巡检（方案 C）
- test/overlay-content.test.mjs：随附用例（npm test = 200 pass / 0 fail / 1 skipped，Node 22）
- scripts/dshlog.mjs（跨机日志取证）、scripts/overlay-entropy.cjs（熵探针）
- dsh-server-docs/04-调整方案/129、133；INDEX.md / docs-manifest.json / 交接单 README 登记
