Cube Sandbox 安全沙箱执行技能。当需要安全执行 Python 代码、Shell 命令，或需要隔离环境运行不受信任的代码时使用。 适用场景： (1) 用户要求"在沙箱中执行代码"、"跑一段 Python"、"安全执行"、"隔离环境运行"； (2) 需要执行可能有副作用的代码（文件操作、网络请求、安装包等），希望通过沙箱隔离风险； (3) 需要读写沙箱内文件、挂载宿主机目录到沙箱； (4) 需要控制沙箱网络策略（完全断网、白名单、黑名单）； (5) 需要暂停/恢复沙箱（保留内存快照以实现快速复用）。 Cube Sandbox 兼容 E2B SDK，通过环境变量 E2B_API_URL 指向 Cube 部署地址即可使用。
