Detailed Description

RusanovFlux (local Lax-Friedrichs): robust flux, compatible with any minimal PhysicalModel.

Fhat = 1/2 (F(UL) + F(UR)) - 1/2 alpha (UR - UL), alpha = max(sL, sR). Only requires model.max_wave_speed – compatible with ANY PhysicalModel of the base concept (no wave_speeds, no pressure). Diffusive (alpha upper bound) but universal. POPS_HD. INVARIANT: component-by-component treatment (scalar upwind), no coupling.
