Purpose

Issue: WalkDirectoryTree in StartPage.xaml.cs adds directory entries even if they contain no .dyn files. It filters .dyn files, but directories are added before checking for children.

This PR improves the sample file directory traversal logic by filtering out dependency folders and empty directories from the sample file tree.

Key Changes:
Adds filtering to exclude directories ending with ".dependencies" from the sample file tree
Implements empty directory filtering by only adding directories that contain .dyn files (directly or in subdirectories)

Summary

Added filtering to exclude .dyn files with "Generative Design" as the active linter.

Changes Made

JSON Handling

• Added using Newtonsoft.Json.Linq; to handle JObject instances from JSON deserialization.

Home Page Filtering Behavior

The home page now filters out:

• Non-.dyn files
• Directories ending in .dependencies or equal to gd
• Directories that don't contain .dyn files

After Fix:
