Unit tests for ideal-gas thermodynamics and eigenvector routines in Gas.hpp.
Tests cover:
- IdealGasThermal: pressure, speed-of-sound, enthalpy from conservative
- Conservative2Primitive / Primitive2Conservative round-trip (2D and 3D)
- PrimitiveGetP0T0: stagnation quantities
- EulerGasRightEigenVector / LeftEigenVector: L*R = I orthogonality (3D)
- IdealGas_EulerGas{Right,Left}EigenVector convenience wrappers
- IdealGasUIncrement: velocity/pressure increments from conservative increments
- GasInviscidFlux / GasInviscidFlux_XY: inviscid flux computation
- GradientCons2Prim_IdealGas: gradient transformation
- GetRoeAverage: Roe-averaged state properties
- IdealGasGetCompressionRatioPressure: positivity limiter
All functions are pure (no MPI, no mesh). Serial doctest.
