BREAKING CHANGE: Removed RedHat/CentOS/Rocky Linux support to improve stability - Remove all RedHat/CentOS-specific code and variables - Consolidate Ubuntu/Debian variables into single debian-family.yml - Simplify CI/CD pipeline (remove CentOS tests) - Remove unstable multi-OS complexity - Update documentation to reflect Ubuntu/Debian focus - Streamline playbooks for better maintainability This change makes the project more stable and maintainable by focusing on the most common server distributions (Ubuntu/Debian) instead of trying to support multiple OS families with different package managers and configurations.
