"""CHV 第三棒（feat-chv-v3）回归测试：WSL 真机 V-1～V-4/F1/F2

实测缺陷的代码层回归。
|
||
|

- V-3① snapshot 传裸 URL（source_url= 是 restore 的键）；
|

- V-3② 快照产物是目录（v54），校验改为目录非空；
|

- V-3③ restore 起 VMM 前清旧 VMM + 旧 socket；
|

- V-3 附带：hibernate 留盘（快照 config.json 引用原盘），
|
||
GC 不删有登记快照的 VM 的盘，restore 前预检快照引用的盘；
|
||
- F1：re-wake 删旧盘（H5 删私钥致新 key 对 + 旧盘 cloud-init
|

不重应用 = host_key_mismatch）；
|
||
- F2：跨实例 stop 按 socket 进程扫描清未登记 VMM；
|
||
- V-4：remote_command source 失败 fail-fast（exit 126），
|
||
guest-env 归 SSH 用户所有；
|
||
- V-1 附带：build.sh 预建 /app/work（1777 粘滞位 + 断言）；

- V-1 附带：host.py default_codex_bin() 走 PATH 查找。
