✨ When file is opened or focused, jump to it in project navigator

**Is your feature request related to a problem? Please describe.**
When a tab is clicked, or a file is opened via the quick open overlay, jump to that file in the project navigator, even if it is layers deep in a nested file structure.

首先跟踪点击标签页和打开 quick open overlay 的流程，然后了解项目导航器如何表示嵌套文件。当打开或聚焦某个文件时，该文件会在导航器中被选中并显示出来（包括深度嵌套的文件），此功能即完成；手动验证两个入口点和嵌套结构。
