Detailed Description

Integration test for the EulerEvaluator pipeline: fdt -> frhs -> fsolve.

Exercises the full evaluator pipeline on three configurations:

1. Isentropic Vortex (NS, 2D periodic, inviscid)
2. NACA0012 (NS_SA, 2D external, viscous + SA turbulence)
3. 3D Box (NS_3D, 3D periodic, inviscid)

For each case the test:

• Reads the JSON config and mesh
• Initializes the evaluator and DOF arrays
• Runs one Newton-like iteration: EvaluateDt -> EvaluateRHS -> LUSGSMatrixInit -> LUSGSForward -> LUSGSBackward
• Measures the L1 RHS norm (golden regression value)

This is an MPI test registered at np=1, 2, 4. Golden value sentinel: 1e300 means not yet acquired.
