Detailed Description

flow — portable (Kokkos) staggered MAC momentum advection (Koren TVD + FOU).

Kokkos port of staggered_advection.cuh: the Koren-limited conservative advection operator and its first-order-upwind variant, on the local extended block (direct strides; ghosts halo-exchanged). The math is a faithful copy (double precision, conservative flux form, +/-2 cell reach). A View accessor replaces the CUDA LocAcc. The functions are KOKKOS_INLINE_FUNCTION so the same code runs on device and is reused by the host reference in the test.
