🧪 Fixup test marks

[joerunde]

Description

Updates pyproject.toml with our test marks to avoid warning spew.

Removes the unused skip_global_cleanup that was leftover from the initial port of test fixtures from vLLM

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀

Shouldn't this be removed as well?

[joerunde]

yeah- we require --forked anyway for any tests where we want to initialize something new on the spyre cards. As far as I know we've never relied on this fixture

[joerunde]

oh interesting, though some of this cleanup may have been doing something for our cpu tests, even though most of them re-use models between tests 🤔

Will need to inspect further next week
