fix: prevent nested folders from receiving special icons.

fix: #525

为嵌套在特殊目录下, 拥有特殊名称的文件夹 (例如 scene/figure) 赋予特殊图标是无意义的.
这么做容易引起混淆, 而且其下的资源也无法使用

Summary of Changes

Hello @fltLi, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在解决一个问题，即嵌套在特殊目录下的文件夹（例如 scene/figure）被错误地赋予了特殊图标。这种行为可能导致用户混淆，并影响其下资源的可用性。通过引入一个检查特殊祖先目录的机制，此更改确保只有顶层或非嵌套的特殊目录才能获得其对应的特殊图标，从而提高了文件图标显示的准确性和用户体验。

Highlights

• 新增辅助函数: 新增了 hasSpecialAncestor 辅助函数，用于检查文件路径中是否存在特殊祖先目录。
• 优化文件类型判断逻辑: 修改了 getFileType 函数，在判断文件类型时，如果文件或文件夹嵌套在特殊目录下，则不再赋予其特殊图标，而是返回 'unknown' 类型，以避免混淆。

Changelog

• packages/origine2/src/utils/getFileIcon.ts
  • 新增了 hasSpecialAncestor 函数，用于检测给定路径中是否存在特殊祖先目录。
  • 修改了 getFileType 函数，在确定文件类型之前，会先调用 hasSpecialAncestor 函数，如果存在特殊祖先目录，则直接返回 'unknown' 类型。

Code Review

这个 PR 旨在防止嵌套的特殊文件夹获取特殊图标。实现上引入了一个辅助函数 hasSpecialAncestor 并在 getFileType 中使用它。这个逻辑是正确的，但目前的实现存在一个关于路径处理的 bug，当路径以斜杠结尾时会导致不正确的行为。我提供了一个建议来修复这个问题。
