I am fully aware of the difference between thermal and mechanical energy, and that the Euler equations effectively only consider mechanical energy balance, not diffusivity

The Euler equations do not have thermal conductivity. Zero viscosity and nonzero thermal diffusivity in NS equations provide energy balance between advection and diffusion. This is very basic stuff
