Detailed Description

CoupledSourceFor / NoCoupledSource: contract of an inter-species COUPLING source.

model.source(U, aux) is PURELY LOCAL (state of a single block only). A multi-species plasma exchanges between species (collisions, charge transfer, friction): S_e depends on U_i, etc. This term does NOT belong in the local PhysicalModel: it is a system-level responsibility. A CoupledSource reads the state of MULTIPLE blocks (+ aux = phi, grad phi) and updates the blocks over a step dt, via the minimal contract apply(system, aux, dt). The skeleton applies it by splitting (additive forward-Euler, SystemCoupler::coupled_source_step). The concrete sources live in adc_cases / the tests (the core stays model-free).
