**Aur builder: add retry logic for yay clone to recover from GitHub 504 errors**
Implemented a robust retry mechanism for cloning the yay AUR helper during Arch dependency installation.
The new logic retries the git clone operation for up to 5 minutes with a 20-second pause between attempts, allowing the build to proceed even when GitHub intermittently returns HTTP 504 errors.

This improves the stability of Arch container builds, especially under network pressure or transient upstream outages.
The yay build process now only starts once the clone step completes successfully.
