feat: standalone 独立安装包集成 + 安装方式选择器 (0.9.4)

- 新增 standalone 安装链路（自带 Node.js，零依赖，无需 npm）
- 安装方式选择器：自动/CDN加速/GitHub/npm 四选一
- 动态查询 latest.json 获取最新版本，不怕旧资源被删除
- GitHub 模式：从 GitHub Releases 下载（CDN 不可用时备选）
- CherryStudio openclaw.exe 干扰过滤
- 默认源改为汉化优化版
- 日志隐藏 R2 下载地址（安全）
- 卸载兼容：standalone + npm 双清理
- 版本检测覆盖所有 standalone 安装路径
- README + 官网添加独立安装包说明
- macOS npm 权限问题通过 standalone 自动解决
