Detailed Description

flow — portable (Kokkos) multigrid transfer operators + projection velocity correction.

Kokkos port of mg_restrict_k / mg_prolong_k (mac_multigrid.cuh) and correct_k (distributed_ns.cuh): per-axis-ratio averaging restriction, trilinear prolongation (added to the fine solution), and the staggered pressure-gradient velocity correction. Faithful copies; per-axis ratio (1 or 2) supports semi-coarsening. Runs on any Kokkos backend.
