 Changed

 - Pre-commit now uses ruff instead of flake8, pydocstyle, pyupgrade and isort.
 - CI now uses GitHub Actions.
 - Docs ported to furo theme.
+- Reimplemented ``find_equations``, ``_volume``, ``surface_area``, ``centroid``,
+  ``_compute_inertia_tensor``, ``rescale``, and ``get_face_area`` methods for convex
+  polyhedra using NumPy vectorized operations and polyhedron simplices.
+- [breaking] ``ConvexPolyhedron._surface_triangulation`` now returns sorted simplices,
+  rather than running polytri. This can change the order of vertices and/or triangles.
+- [breaking] ``faces`` may return faces in a different order than previously. Faces are still sorted with ``sort_faces``, and will still be ordered such that curl and divergence theorems work properly.
+- ``volume``, ``surface_area``, and ``centroid`` properties now return stored values, rather than computing the quantity at each call.
+- ``rescale`` now computes the centroid to ensure the correct value is available when ``centroid`` is called.
+- Optimized pytest configurations for more efficient use of local and remote resources.
