Detailed Description

Option struct for the explicit finite-volume 1D network solver.

Mirrors the role SolverOptions2D plays for the 2D marcher: a plain value type carrying every knob the solver reads, populated from the FV_* keys in [OPTIONS] (OptionsHandler.cpp) and stored as an embedded member of SimulationOptions.

Dependency-free by design (no SimulationContext, no Kokkos) so the GPU plugin can include it across the plain-C ABI boundary.
