Detailed Description

Physics model definitions for the EulerP module: gas properties, state conversions, and inviscid flux computation.

Provides:

• PhysicsParams: POD struct of gas parameters (gamma, viscosity, specific heats), JSON-serializable.
• PhysicsDeviceView: Device-callable view with conservative/primitive conversions and thermodynamic relations.
• Physics: Host-side physics object managing device transfer of reference values.
• GasInviscidFlux_XY: Device-callable inviscid flux projected onto a face normal.

Note

In EulerP, the primitive state stores internal energy (rho*e) at index I4, NOT pressure. This differs from the Euler module convention.
