请协助我清理当前机器上的垃圾文件，目标系统是 <Windows 11 / Ubuntu 26.04 / macOS 26>。
要求：
1. 不允许联网下载第三方清理工具，不允许调用不明脚本。
2. 不允许删除用户文档、照片、浏览器 Profile、密钥、证书、虚拟机镜像、业务数据目录。
3. 先识别系统版本、磁盘占用、主要缓存/日志/临时目录，只输出脱敏结果。
4. 先生成 dry-run 清单，列出将要清理的路径、类型、估算大小和风险等级。
5. 在我明确确认前，不允许真正删除。
6. 确认后只执行内置工具和本文脚本：Windows 使用 PowerShell 与 cleanmgr；Ubuntu 使用 apt-get、journalctl、find、snap；macOS 使用 zsh、find、Trash/Caches/Logs。
7. 清理后输出前后空间对比、失败项、跳过项、后续人工检查建议。
8. 最终报告中不要出现完整 IP 地址、完整计算机名、私有域名、token、密码、密钥或真实用户名。
