v9.3.0

@adtzlr

[9.3.0] - 2025-06-29

Add Mesh.add_points(points) to update the mesh with additional points.
Add Mesh.clear_points_without_cells() to clear the list of points without cells (useful for center-points of multi-point constraints).
Release FElupe on conda-forge, starting with v9.2.0.
Add ConstitutiveMaterial.is_stable() which returns a boolean mask of stability for isotropic material model formulations. Note that this will require an additional volumetric part of the strain energy density function for hyperelastic material model formulations without a volumetric part.
Add the linear-elastic material formulation constitution.LinearElastic1D() and a truss-body mechanics.TrussBody().
Add RegionTruss with a truss element. This is a line element with a GaussLobatto(order=0) quadrature, i.e. with two quadrature points located at the boundaries.

Change the required setuptools-version in the build-system table of pyproject.toml to match PEP639 (setuptools>=77.0.3).
Change the labels to well-known labels for the URLs in pyproject.toml.
Change the first return value of ViewMaterial.uniaxial(), ViewMaterial.planar(), ViewMaterial.biaxial(), ViewMaterialIncompressible.uniaxial(), ViewMaterialIncompressible.planar(), ViewMaterialIncompressible.biaxial() from the stretch to a list of all three principal stretches.

Fix the declaration of the (spdx identifier) license and license-file in pyproject.toml.
Fix missing import of TriQuadraticHexahedron in the top-level namespace.
Fix the path to docs/_static/logo_without_text.svg in docs/conf.py.
Fix a typo in the docstring of MeshContainer.from_unstructured_grid().
Fix CompositeMaterial for input lists of length 1.
