Refactored build.func to use a unified install.func for all supported OS types, simplifying OS detection and package installation. Added cleanup_lxc step to all install scripts. Removed support for runit, pacman, and nix-env from install.func, and improved SSH server installation logic for containers. Updated template pattern matching for additional OS types.
Eliminated explicit dependency installation and cleanup steps from all distribution-specific install scripts. This streamlines the scripts and delegates dependency management and cleanup to other processes or steps.
Introduces container setup scripts and install scripts for AlmaLinux, CentOS Stream, Devuan, Fedora, Gentoo, openEuler, openSUSE, Rocky Linux, and updates Alpine install script. Adds corresponding JSON metadata files for each distribution in the frontend. These changes enable streamlined LXC container creation and installation for a wide range of Linux distributions.
