Enhance setup scripts to detect OS and determine package manager

- Improved OS detection in bootstrap.sh and setup.sh to handle unsupported OS cases.
- Added a function to determine the package manager (nala, dnf, apt) based on the detected OS.
- Updated package installation commands to use the appropriate package manager.
- Enhanced user feedback with colored output for better visibility during setup and updates.
