This commit adds a pin to `matplotlib==3.10.9` in the `dev` extra dependencies. Matplotlib 3.11.0 introduces visual changes that break our graphical-regression tests. As we do for other packages whose new releases can break the test suite, we pin a precise version in the `dev` extra to ensure reproducible CI while keeping the package unpinned in the default dependencies so users can choose whichever version they prefer. We pin `3.10.9` instead of the newer `3.11.0` because the latter drops support for Python 3.11, which we continue to support until its official end-of-life (October 2026): https://devguide.python.org/versions/

We cannot run `pytest --mpl` in `test_minimal` (without extra), since the visualization output depends on the version of Matplotlib, and the pinning is only in the `dev` extra.
