Subject: [PATCH] Add shallow fetch to improve performance for large
 repositories

This change adds `--depth=1` to git fetch operations to perform shallow
fetches instead of full history downloads. This significantly reduces
checkout time for large repositories as reported in issue #52.

Changes:
- Line 55: Added --depth=1 to PR branch fetch
- Line 102: Added --depth=1 to new branch fetch

Fixes #52
