"""Integration test for external editor GUI functionality.

These tests verify that the external editor configuration is properly
loaded and the patch modal shows the option to open in external editor.

Manual verification:
1. Run: uv run sloppy.py
2. Ensure config.toml has external editor configured
3. Have an agent/Tier 4 generate a patch  
4. Click "Open in External Editor" in the patch modal
5. VSCode should open with diff view showing original vs modified
