Automatic Upstream Branch Setup

What: Automatically configures upstream tracking after git checkout

How it works: After checking out a branch, automatically runs:

git branch --set-upstream-to=origin/<branch> <branch>

Details:

• Checks if upstream is already configured
• Verifies remote branch exists before setting upstream
• Logs all actions for debugging
• Called automatically after branch checkout operations
