feat: SSHClient v1.0.0 - PyQt5 + paramiko 跨平台 SSH 客户端
功能: - 多主机管理 (增删改查, 密码/私钥双认证, 导入导出) - 远程终端 (命令执行 + 常用命令快捷栏 + 超时控制) - SFTP 文件浏览 (上传/下载带进度, 新建/删除/重命名) - 实时监控 (CPU/内存/磁盘/网络, 1-10秒可调刷新) - AI Agent (OpenAI 兼容 API, 5 工具自动调用: 命令/指标/列文件/读文件/上传) 技术栈: PyQt5 + paramiko + psutil + requests + PyInstaller 打包: build_windows.bat / build.sh 一键产出 ~57MB 单文件 exe 测试: core 6/6 + UI 3/3 + E2E 6/6 全部通过
