Add an option to show/hide hidden folders in the file tree

Feature Request

Now that the file tree/sidebar has returned, it would be very useful to have an option to show or hide hidden folders (dot folders) such as:

• .git
• .vscode
• .idea
• .next
• node_modules

Many projects contain a large number of generated or tooling-related directories that make the sidebar noisy and harder to navigate.

Suggested behavior:

• Add a setting or toggle for showing hidden folders/files
• Allow users to collapse or completely hide specific folders from the sidebar
• Similar to VSCode explorer exclude behavior

This would make navigating large repositories much cleaner and improve usability significantly.
