host 1c8fc3f7c8 对齐 Muse P4：浏览器完全对齐（CDP broker 单元外 + a11y-tree-only + 确定性分类器） 
- chv-guest/chv-cdp-broker.py（新）：单元外 CDP broker，用户 chv-browser，
  独家 chromium.launch(headless=True, args=LAUNCH_ARGS)；启动参数白名单
  无 --remote-debugging-port、无 devtools；导航前 URL 校验 + 拦截名单；
  快照恒带 untrusted_input 与 injection_flags；高风险表单在页时 open
  即 ask 入队；观测到导航 POST 自动暂停；命中拦截规则的下载取消 + 暂停
  + ask；全部回包与错误经 sanitize_error + response_leaks 检查。
- chv-guest/chv-browser.py（P2 版重构）：改为 broker 客户端，不再直连
  Playwright（本文件无 playwright import），保留 URL 校验 + 快照截断
  作为第二层防线；暂停状态与 broker 同步。
- chv-guest/chv_browser_guard.py（新）：纯 stdlib 共享规则——validate_url、
  拦截名单加载/匹配、快照截断、错误消毒（去 HTML、截断 200 字符、凭据形
  key=value 与 sk- 形 token 打码）、注入启发式（中英文各 6 条）、表单风险
  扫描、下载扫描（可执行扩展名）、文件型 ask 队列（pending/allowed/denied，
  与 P3 ApprovalQueue 同语义）、启动参数与回包泄露检查、脚本注入面
  禁止清单（FORBIDDEN_PAGE_ATTRS/FORBIDDEN_OPS）。
- chv-guest/browser-blocklist.txt（新）：静态拦截名单；首版只有 RFC 2606
  .test 自测条目，生产条目由运维构建时填入，无在线更新。
- chv-guest/build.sh/buildinfo.py：P2 三脚本 + P4 三文件纳入镜像与
  buildinfo；新增 chv-cdp-broker.service 与 /run/chv/ask-queue tmpfiles。
- docs/chv-muse-p4-gap.md（新）：现状 vs Muse 官方要求差距表、改动、
  诚实边界、P2 合入约定、真机待验证清单（round 12）。
- docs/chv-production-readiness.md：补 §15（P4 一节；编号合入时若与
  P2 的 §15 撞，顺延）。
- cloud/tests/test_chv_muse_p4.py（新，36 项）：guard 单元、AST 钉住
  禁止属性、假 Playwright broker 测试、假 broker agent 测试、真 Unix
  socket 联调、buildinfo/build 干跑断言；含否定测试（evaluate 被拒、
  DOM 外泄被拒、DevTools 不可达、私有地址被拒、高风险表单被拦、
  注入文本被标注）。

测试：P4 新测试 36/36；全量 cloud 套件 1903 项，两次连续全过
（skipped=8）。附记：第一次全量跑出 1 个失败但输出未保留、后两次
均未复现，疑为时序抖动，未追认。
真机验证未做：排队等 round-11/第三棒释放 100.65.51.33，清单见 gap
表 §5。本地提交，未推未合未部署。
