feat: 新增 file/svc/archive/sys/log/fw 分组并扩充 net、proc

- file：findbig 按大小、findrecent 按修改时间、findname 按名称查找文件 - svc：systemctl / launchctl / sc 统一接口，status、enable、disable、logs - archive：按扩展名自动识别格式并解压，支持 tar.gz/tgz/tar.bz2/tar.xz/tar/zip/gz - sysinfo：OS、CPU、内存、磁盘一览 - log：journalctl / log show / wevtutil 搜索关键字与查看最近日志 - fw：ufw / firewalld / iptables / ALF / netsh 统一接口，status、allow、deny - net 新增 ping、trace（mtr 优先）、dns（dig 优先）、curl HTTP 诊断 - proc 新增 topmem、topcpu、killname - 危险操作（svc enable/disable、proc killname、fw allow/deny）需 --yes 确认 - 注册表、executor 派发表、cli 分组说明与 README 同步更新
