Fix `stdout`/`stderr` redirects

[kenodegard]

Resolves #24

Changes include:

• Ruff version bump and enabled some additional lints (happy to remove these changes if undesired)
• Add a TDD test used to showcase problematic behavior
• ~Call item.ihook.pytest_runtest_call(item=item) instead of directly calling item.runtest() to benefit from pytest's automatic handling of sys.last_type, sys.last_value, sys.last_execption (apparently not handling this causes stdout/stderr to be redirected and inaccessible within tests, see https://github.com/pytest-dev/pytest/blob/3b798e54221f1895a983000c7e5bc8afdacd5011/src/_pytest/runner.py#L165-L182)~
• Switch from pytest_runtest_protocol hook to pytest_pyfunc_call hook (deeper in the call stack, pytest_pyfunc_call is invoked from runtest which in turn is called from pytest_runtest_call)

@art049 anything more to do here?

It's a bit annoying that formatter changes and logic change are in the same PR in the end. I'll maybe try to split things out.
