host 81e4eaf4db feat(chv): 对齐 Muse P6 privsep worker + 确定性安全检查层 
- cloud/chv/privsep.py（新）：Gitea worker 注册表（凭证白名单只含
  GITEA_TOKEN）+ 类型化请求/响应（request_id 绑定、64KB 上限）+
  Unix socket 客户端（超时/崩溃 -> 类型化失败 WorkerRefusal）+
  客户端白名单校验
- cloud/chv/safety.py（新）：UntrustedData 来源标记 +
  InjectionScanner 确定性规则（block/flag/allow，中英）+
  redact_secrets + AuditLogger（只记指纹，不记值）+
  audit_inference_request/response
- chv-guest/chv-gitea-worker.py + .service（新）：systemd 沙箱化
  worker（SO_PEERCRED 只放 root，仓限 ~/workspace，git 只配 authd
  helper，绝不持 token；输出先扫描再返回）
- chv-guest/chv-sync-worker-client.py（新）：agent 侧薄 CLI
- chv-guest/chv-sync.sh：pull/push/status 有 socket 时走 worker，
  否则旧路径 + stderr 警告（过渡兼容）
- cloud/chv/executor.py：_run_guest 前后加推理边界审计钩子
  （best-effort）
- docs/chv-muse-p6-gap.md（新）：差距表 + 覆盖边界 + 真机待验证清单
- docs/chv-production-readiness.md：§15
- cloud/tests/test_chv_muse_p6.py（新）：43 项

测试：新测试 43/43；全量 cloud 套件 1910 OK（skipped=9）；mypy
在新增文件上干净（剩余 4 处为基线旧错 executor.py:1396/1401、
marker_tools.py:142，未动）。
真机验证：未做，排队在 round-11 之后，清单见
docs/chv-muse-p6-gap.md §4。

"""对齐 Muse P6 测试：privsep worker + 确定性安全检查层。
只用标准库与 mock，绝不启动真实 VM、不联网、不含真实 token
（测试值全是假值）。覆盖：
- 安全检查层：注入规则每档至少一个 block/flag/allow 用例（含中英）、
真实 git 输出样式不误报、脱敏全模式、来源标记随数据走、审计里
绝无密钥值、审计失败不中断；
- privsep 协议：请求/响应校验、白名单（客户端与服务端各拒一次）、
仓库 confinement、超时与 worker 崩溃 → 类型化失败；
- worker 真 socket 回路：pull/push/status/ping、唯一仓解析、helper
缺失 fail-closed、git argv 里只有 helper 配置绝无 token、输出先
扫描后返回、block 阻断、flag 标记；
- chv-sync.sh 委托：worker 在时走 worker、不在时走旧路径 + 警告；
- 执行器推理边界审计钩子：只记指纹、不记值、失败不中断。
