merge(chv-muse-round12): 合入 P4 浏览器完全对齐 (1c8fc3f)
冲突按并集解：build.sh 保留 P3 authd 检查/拷入/runcmd（含 start chv-authd）+ P4 三件套检查/拷入（P4 的重复 runcmd 行 删掉——同一文件写两次会盖掉 authd 启动行）+ P4 的 cdp-broker.service/tmpfiles（含 ask-queue）+ P3 叶子模块条件 拷入；buildinfo.py 两边内容项并集；chv-browser.py 取 P4 重构 版（broker 客户端）；production-readiness.md P4 的 §15 顺延为 §16。P2 的 BrowserTest 改走假 CDP broker（断言不变），两路 干跑夹具补齐并集文件集。
