Remove unused utility functions and decorative output

This commit cleans up several scripts by removing:
- Decorative color and header output from install.sh
- OS version display in setup.sh
- Unused utility functions in utils.sh related to SSH key setup, package management, and GitHub version retrieval

The changes simplify the scripts and remove unnecessary code while maintaining core functionality.
