Detailed Description

Regression tests for CFV VariationalReconstruction<3> (3D).

Exercises the full 3D VR pipeline on a periodic hex mesh:

Mesh reading, partitioning, ghost building
VR construction: metrics, base+weight, rec coeff
Polynomial exactness: constant (P0) for all methods
Iterative VFV convergence and error measurement

Uses the Uniform32_3D_Periodic.cgns mesh (32^3 = 32768 hex cells, periodic on [0,1]^3).

Golden values are acquired on first run and must be captured manually. The test verifies the 3D template instantiation works end-to-end.
