主菜单

选项	功能	说明
1	上传文件到服务器	直接通过 rz 选择单个文件上传
2	下载文件到本地	通过 sz 下载文件到本地
3	选择文件下载	交互式多选文件下载，支持序号/范围/逗号分隔
4	批量上传多个文件	rz -bye 批量上传模式
5	上传文件夹压缩包	上传 ZIP/TAR 压缩包后自动解压
6	下载文件夹压缩包	选择文件夹压缩为 tar.gz/zip/tar.bz2/tar.xz 后下载
7	创建测试文件	创建 1KB/1MB/10MB/自定义大小测试文件
8	清理临时文件	查找并清理 .tmp/.temp/.swp 等临时文件
9	检查终端 Zmodem 支持	检测 lrzsz 安装状态和终端兼容性
10	查看传输历史记录	显示最近修改文件和大文件列表

功能特点

文件上传：rz 上传单个或多个文件到服务器当前目录
文件夹压缩上传：上传 ZIP/TAR 压缩包后自动解压，支持 zip、tar.gz、tar.bz2、tar.xz、tar、gz 格式
文件夹压缩下载：选择文件夹并压缩为 tar.gz/zip/tar.bz2/tar.xz 后下载到本地
交互式文件选择：支持序号、范围（1-5）、逗号分隔（1,3,5）多种选择方式
批量操作：rz -bye 一次选择多个文件上传
测试文件创建：快速生成 1KB~10MB 的测试文件用于传输验证
临时文件清理：自动查找 .tmp、.temp、.swp、.swo 等临时文件并清理
Zmodem 支持检测：检测当前终端是否支持 Zmodem 协议及推荐配置
自动安装依赖：自动检测并安装 lrzsz、bc 等依赖包，支持 apt/yum/dnf/apk/pacman/zypper/opkg/pkg 多包管理器

注意事项

需要终端软件支持 Zmodem 协议（MobaXterm/Xshell/SecureCRT/Tabby/WindTerm 等）
PuTTY 不支持 Zmodem 协议，Windows Terminal 需要额外配置
上传大文件时请确保网络稳定性
压缩下载会占用临时磁盘空间，下载完成后可选择删除临时压缩包
使用 list_dir_colorful() 函数美化显示当前目录文件列表
