Resolves: #472 (based on the approach 2 mentioned in #472)
Better/Simpler Implementation of #473.

On MacOs virtual Machine

On Ubuntu virtual Machine (Simple Nix installation)

This is the right direction, but still doesn't quite capture the nix --version parsing as single action; this command is now being run twice now (as can be seen in your screenshot).

This is a big problem with using LLM to generate code. I'd suggest discarding it and rewriting from scratch as iterating further can be a waste of time.

So which type best captures the output of nix --version? Perhaps something like:

data NixVersion = NixVersion_Official VersionSpec | NixVersion_DetSys { detSysVersion :: VersionSpec, nixVersion :: VersionSpec

A human can do better here. Types should be modelled based that which they are actually modelling, rather than to fit an existing implementation.
