使用说明: $(basename "$0") [选项]

选项:
    --all         运行所有检查 (M-013~M-017)
    --m013        运行M-013凭证泄露扫描
    --m014        运行M-014入站覆盖率检查
    --m015        运行M-015直连检测
    --m016        运行M-016 Query Key拒绝检查
    --m017        运行M-017依赖审计四件套
    -v, --verbose 详细输出
    -h, --help    显示帮助信息

示例:
    $(basename "$0") --all
    $(basename "$0") --m013 --m017
    $(basename "$0") --all --verbose

退出码:
    0 - 所有检查通过
    1 - 至少一项检查失败
