停止当前 mihomo（通过 ${PID_FILE} 记录的 pid）
env
输出代理环境变量 export 片段
用法示例：
eval "\$(mh env)"
mode [rule|global|direct]
切换当前 profile 的运行模式，并重启
- rule 使用内建基础规则
- global 全部走代理
- direct 全部直连
rules [show|reset]
查看或重置当前 profile 的基础规则
- show 显示当前规则
- reset 写回一套最简规则，并切回 rule 模式
doctor
输出当前 mh/mihomo 的诊断信息
- capability
- 端口监听
- TUN/模式/代理环境
- API / 路由 / DNS
- 最近日志
tun [on|off|toggle]
开关 TUN（会写入当前 profile 的 config.yaml 并重启）
- 开启 TUN 通常需要 sudo/root 或给 mihomo 加能力：

Notes:
- API 不通时，很多功能会失败：确保 mihomo 正在运行且 external-controller 为 ${API_HOST}:${API_PORT}
- 如果刚启动就查询失败，wait_api 会稍等 mihomo API 就绪（避免 race）
- `mh` 是子进程，不能直接修改你当前 shell 的代理环境；需要 `eval "\$(mh env)"` 或写入 rc 文件
