Detailed Description

Serial/OpenMP CPU reference implementation of the explicit FV 1D solver.

Godunov-type explicit finite volume on the conduit cell mesh: hydrostatic (Audusse) reconstruction → HLLC face flux → positivity limiting → flux divergence with the bed-slope correction → semi-implicit friction → explicit zero-D node continuity. Substeps at the CFL limit to fill each routing step.

This is the REFERENCE implementation in the plan's sense: the Kokkos plugin compiles the same FvKernels.hpp bodies, and the §6.8 parity harness diffs the two element-wise.
