JOJO c2d460a706 feat: 宿主机模式网络沙箱
- macOS sandbox-exec profile 支持 network_permission 参数 (restricted/full/none)
- backend: 透传网络权限至 run_command / terminal_session / sub_agent / background_command
- 后台 run_command 接入沙箱执行
- 自动审核模式兼容网络权限报错 markers
- 运行时切换网络权限通过 pending 机制 + user 消息通知
- 提示词注入网络状态 (仅沙箱模式)
- 前端权限菜单新增网络权限组 (受限/完全开放)
- direct 模式下网络权限组变灰禁用
- settings.json 默认 HOST_SANDBOX_NETWORK_PERMISSION=restricted
