Detailed Description

Aux-component-aware variants of the native Schur kernels (coupling/schur/core/schur_condensation.hpp.

condensed_schur_source_stepper.hpp). The native kernels read B_z from a DEDICATED B_z MultiFab at component 0; a compiled Program reads B_z straight from the System aux channel at an arbitrary component c_bz, so these thin wrappers carry c_bz and otherwise REPRODUCE the native formulas verbatim (same LorentzEliminator B^{-1}, same coefficients, same centered gradient) – the native CondensedSchur path is untouched. Named functors (device-clean, nvcc cross-TU rule, like the native ones). epic ADC-399 / ADC-421. A_op = I + c*rho*B^{-1} per cell (eps_x/eps_y diag, a_xy/a_yx cross). Mirrors detail::SchurOperatorCoeffKernel but reads B_z from the aux at c_bz.
