This is a useful piece of functionality to being able to eat URL
hyperlinks, for instance, which is a bug that Lix has while dealing with
terminal output today.

This commit makes Lix include the summarized content of the value being
indexed when it is bad.
lix/lix2 » nix eval --expr '{x.y = 2;}' 'x.y.z'
error: the value being indexed in the selection path 'x.y.z' at 'x.y' should be a set but is an integer: 2
lix/lix2 » nix eval --expr '{x.y = { a = 3; };}' 'x.y.z'
error: attribute 'z' in selection path 'x.y.z' not found inside path 'x.y', whose contents are: { a = 3; }
Did you mean a?
lix/lix2 » nix eval --expr '{x.y = { a = 3; };}' 'x.y.1'
error: the expression selected by the selection path 'x.y.1' should be a list but is a set: { a = 3; }

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.

I don't know what the heck the xonsh module is doing but its obviously
crimes so it has to go. It was never intended to be running here anyway.

There is absolutely no good reason these should show up in NARs besides
misconfigured systems and as long as the case hack exists, unpacking
such a NAR will cause its repacking to be wrong on systems with case
hack enabled.
This should not have any security impact on Lix to fix, but it was one
of the vectors for CVE-2024-45593:

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.

This is capped at 12 because 3.7 seconds of startup is painful enough
and 5.5 seconds with 24 was more annoying.

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.
