fix: 修复 Release 正文为空及检查更新 v0.1.0 404 问题

- CI: /tmp/release-notes.md 改用 $RUNNER_TEMP，修复 Windows 路径不一致导致
  release body 显示为 commit message 而非 CHANGELOG 内容
- 删除远端 v0.1.0 tag（早期测试遗留），修复 electron-updater 从 Atom feed
  读到 v0.1.0 > v0.0.4-beta 后尝试 latest.yml 而 404 的检查更新失败
- 关于页面新增应用文件夹、数据文件夹、日志文件夹展示，带复制和打开按钮
