Currently the Command and CommandResult classes are mixed into the nix
fixture file.
This commit moves them out into their own lib file, to make it more
obvious that they can be used standalone for other applications too
Additionally improved documentation of said classes
and bumped log level of stdout and err on unexpected exitcodes, as it is
within an error context

Due to nix-store making its paths read-only, pytest was unable to remove
the test files and hence the entire temporary directory, screaming all
over the place in stderr about that, getting worse for each test run.
By making the nix fixture first yield nix and then, after the test
finished running, changing the file permissions to include read on all
files and directories within the temp folder, pytest is able to properly
remove old test runs again
Additionally added more clear instructions for file deletion to the
pytest configuration

Add a snapshot fixture, which allows comparing and updating strings
against external files

Use logger in favor over print statment.
This is explicitly supported and encuraged by pytest, which also allows
for capturing logs separate from stdout calls, which is handy for when
e.g. lix code calls out to stdout to keep those differentiated from test
output

separating the nix fixture from the __init__.py file to increase
readability and overview over the existing fixtures

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.

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.
