Pull Request Overview

This PR fixes two issues related to package management: a bug where .git/config could be corrupted with download links instead of proper git URLs, and elimination of error messages when cmds/.config doesn't exist.

• Adds proper validation for git URLs before attempting to restore origin remotes
• Implements graceful handling when the environment config file is missing
• Introduces a helper function to safely determine appropriate git URLs for restoration

Catching bare Exception is too broad. Consider catching more specific exceptions that get_url might raise to avoid masking unexpected errors.
