External user configuration module. Can be:
- A path to a local module directory
- A fetchGit/fetchTarball result pointing to a repository
The external module can contain:
- user.nix (optional): Sets athenix.users.<name> options AND home-manager config
- nixos.nix (optional): System-level NixOS configuration
Example: builtins.fetchGit { url = "https://github.com/user/dotfiles"; rev = "..."; }
