Description

The Cell class in mesa/discrete_space/cell.py currently uses a manual implementation for getstate to handle serialization (pickling). It intentionally clears the connections attribute to avoid infinite recursion during deepcopy operations.

The code currently contains a FIXME indicating this logic was a temporary workaround for older Python versions:

# fixme, once we shift to 3.11, replace this with super. __getstate__

Context

The project's pyproject.toml now sets requires-python = ">=3.12", meaning the legacy workaround is no longer necessary.

Task

Refactor the getstate method in mesa/discrete_space/cell.py to:

1. Remove the manual dictionary construction.
2. Utilize super().__getstate__() to retrieve the default state.
3. Ensure the logic that clears the connections dictionary is preserved to prevent recursion errors.
