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

Ruff is used to enforce our code-style for the python parts of the
reposity, similar to clang-tidy for the cpp parts.
This includes a pre-commit hook to format code before it is committed
When "unfixable" - i.e. no autoformatting is available - the commit is
rejected

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

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.
