"""常驻：确保本机有一个可用的独立 Chrome 实例（9223，固定 profile ⇒ 登录态保留）。
|
|
|
|
为什么必须常驻：本机沙箱在父进程退出时连带杀子进程 ⇒ 会话/工具调用里起的浏览器一返回就死。
|
|
为什么放工作区根而不是 tmp/：tmp/ 会被清理，脚本一没计划任务就静默失效。
|
|
|
|
形态：幂等 —— 端口已在听 ⇒ 立刻退出（⛔ 不叠加第二个实例、不抢同一个 profile）。
|
|
由计划任务 `bh-chrome-keepalive` 每 5 分钟触发一次（MultipleInstances=IgnoreNew），
|
|
所以"活着的那份"负责守端口，任务只是兜它挂掉时重新拉起。
|
|
⛔ 不附着用户日常 Chrome（那是 9222，会弹「允许远程调试？」动到用户浏览器）。
