使用 start_new_session=True 启动 Chrome，使其成为独立进程组的领导者。 在 openclaw、Claude Code 等 Agent 平台中，命令执行完毕后平台会 清理整个进程组，导致 Chrome 子进程随之退出。 加入此参数后 Chrome 与 Python 父进程解耦，可在后台持续运行， 支持跨命令复用同一 Chrome 实例。

问题
在 openclaw、Claude Code 等 Agent 平台中执行 skill 命令时，
平台在命令结束后会清理整个进程组（SIGTERM/SIGKILL），
导致通过 subprocess.Popen 启动的 Chrome 子进程随之退出。
表现为：每次调用 CLI 命令后 Chrome 自动关闭，
下一条命令不得不重新冷启动 Chrome，增加延迟且体验差。
修复
在
launch_chrome()的subprocess.Popen中加入start_new_session=True。这会让 Chrome 成为新进程组的领导者，与 Python 父进程完全解耦。
父进程（或其所在进程组）被终止时，Chrome 不受影响，可持续在后台运行，
实现跨命令复用同一 Chrome 实例。
影响范围
仅影响
launch_chrome()的启动行为，对 CDP 连接、端口复用逻辑无任何改动。
