Detailed Description

HLLCFlux (HLL + Contact wave, Toro): 3 waves, resolves the contact discontinuity.

GENERIC when the model satisfies HasHLLCStructure (contact_speed + hllc_star_state): applies F* = F_k + s_k (U*_k - U_k) with no layout or EOS assumption. Otherwise falls back to a canonical Euler 2D path (n_vars == 4, normal/tangential momentum by dir, star speed sStar via Toro's formula eq. 10.37), which requires model.pressure and model.wave_speeds and returns FL / FR in the supersonic region. POPS_HD. INVARIANT: the n_vars == 4 assumption applies ONLY to the Euler fallback branch.
