Migrate to another framework

[yipengsun]

digga is no longer maintained: divnix/digga#503

I need to switch to another framework. maybe flake-parts?

• Define some digga-like profiles and suites
• Export NixOS machines (meaning, there's a system builder that collect attrs defined in flake.nix and export a nixosConfigurations.<hostname>)
• Export darwin machines will use a separate issue.
• Convert NixOS config to a colmena one not a priority. Will use a separate issue.

Probably overriding flake-parts like this;

    flake-parts = {
      url = "github:hercules-ci/flake-parts";
      inputs.nixpkgs-lib.follows = "nixpkgs";
    };

Perhaps this example is more useful, as it includes home-manager related bits: https://gitlab.com/coffeetables/higher/-/blob/master/flake.nix?ref_type=heads

Will use colmena to define profile for each machine. However, it doesn't support nix-darwin as of now: zhaofengli/colmena#125

Or, use https://github.com/yelite/lite-system instead, as that is simpler, and it has macOS support.

There's already a way to convert nixosConfiguration to colmena: zhaofengli/colmena#161 (comment)

We can get rid of homeage: ryantm/agenix#50 (comment)

Finally got a WSL NixOS machine that mostly works, with my latest 'framework'.
