Detailed Description

flow — portable (Kokkos) native per-face domain boundary conditions for the MAC grid.

Kokkos port of mac_bc.cuh: fill the NON-periodic boundary face/ghosts the halo leaves untouched. Each kernel runs over the boundary face's perpendicular (b,c) plane; one thread owns a column and writes its own ghosts (disjoint, no races). MAC staggered convention: component a is stored at the -a face of its cell. Faithful copies of the reflection / fold / outflow logic. Scalar wall velocity (the per-position inlet-profile variant is a later specialization). Runs on any Kokkos backend.
