I want this for being able to write reasonable expect-test style tests
for oneliners. We will still probably want something like insta for more
complicated test cases where you actually *want* the output in a
different file, but for now this will do.

This also rewrites a lot of the command handling in the fixtures
library, since we want to more precisely control which way that the nix
store is set up in the tests, rather than the previous method of
renaming /nix/store to some temp dir (which allows builds but does not
allow any /nix/store paths or stability across runs, which is a
significant issue for snapshot testing).
It uses a builder to reduce the amount of state carelessly thrown
around.
The evil NARs are inspired by CVE-2024-45593
(https://github.com/NixOS/nix/security/advisories/GHSA-h4vv-h3jq-v493).
No bugs were found in this endeavor.

I am tired of bad shell scripts, let me write bad python quickly
instead. It's definitely, $100%, better.
This is not planned as an immediate replacement of the old test suite,
but we::jade would not oppose tests getting ported.
What is here is a mere starting point and there is a lot more
functionality that we need.
