mypy ignoring cloudpickle as it's untyped

[jamesbraza]

This fixes an error we see when locally running mypy -p aviary:

src/aviary/tools/server.py:35:1: error: Skipping analyzing "cloudpickle": module is installed, but missing library stubs or py.typed marker  [import-untyped]
            import cloudpickle as pickle
    ^
src/aviary/tools/server.py:35:1: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports

Using uv run pre-commit passes normally on my end.

Yeah it's because pre-commit's mypy doesn't have cloudpickle in its additional_dependencies. If you locally used mypy in a virtual env with the full dev dependencies, you'd hit this error (and a bunch of others)
