Description

This quick PR switches the XDGMesh over to using num_volume_element_faces() (a new API in XDG) for counting surface bins in a volumetric mesh.

Summary by CodeRabbit

• Bug Fixes
  • XDG mesh initialization now uses the surface-bin count reported by the mesh manager, keeping bin totals consistent with the mesh data.
  • Initialization no longer stops with an unsupported-element error from the previous local counting process.

with XDG revisions lacking mesh_manager()->num_volume_element_faces(): retain
the previous face-counting fallback or gate the method call with a CMake feature

Walkthrough

XDGMesh::initialize now gets the surface-bin count from the XDG mesh manager. It removes manual counts for tetrahedra and hexahedra, along with the fatal error for unsupported element types.

Changes: XDG surface-bin count

Layer / File(s)	Summary
Use manager face count src/xdg.cpp	XDGMesh::initialize uses the mesh manager’s face count and removes element-specific counting and the unsupported-element error.

XDG commit 83efb30 lacks this method, so an existing XDG-enabled build fails to compile. Both that commit and the commit adding the method report version 0.14.1, so a version check alone cannot distinguish them. (raw.githubusercontent.com)

Keep the previous counting fallback or add a CMake feature check and document the required XDG revision.

Simple enough! Thanks for adding these methods into XDG itself as well @nuclearkevin.
