Detailed Description

Linear two-fluid isothermal electrostatic kernel (TwoFluidLinear): VALIDATION/REFERENCE.

Canonical home of the validation/reference bricks (ADC-329): kept OUT of the production brick surface and exposed under namespace pops::validation. Generalizes LangmuirMode to two mobile species (electrons omega_pe + ions omega_pi) with isothermal pressures. Lets you check the electrostatic dispersion branches (w_fast Langmuir, w_slow ion-acoustic). Not used by adc_cases as of 2026-06-06. The legacy path <pops/physics/two_fluid_isothermal.hpp> still works through a compat forwarder.
