Add more & generalize flake outputs:
- templates: just a `default.nix` (TODO: add a `Haskell` template)
- packages & devShells: create and use `forEachPkgs`
Add more `Wayland` things for `homix`:
- `swww` - custom package + custom systemd service (TODO: abstract away)
- `wired` - from flake + `home-manager` module
Add default `imports` and `nixokgs.overlays` for `reo101@homix`
-- TODO: don't handwire it, somehow *auto-import* from `mkNixosHost` in `flake.nix`
Copy and impove `home-manager` module integration from `nix-on-darwin` for `nixos`
Add `homix` *server* with NVIDIA drivers, `wayland` + `river`, Jellyfin, etc.
