Contact-discontinuity advection with GSPH (exact Riemann solver + Inutsuka V2)#

Advects a density jump at uniform velocity with equal pressure on both sides. Since \(p_L=p_R\) and \(u_L=u_R\), the exact Riemann solution at the interface is a pure contact discontinuity: no shock or rarefaction forms, and the analytic solution is simply the initial density jump translated rigidly at speed \(u_0\). This isolates how much a scheme numerically diffuses a density (compositional) interface carried by a uniform flow, independent of any shock-capturing behaviour.
