Detailed Description

flow — portable (Kokkos) geometric multigrid V-cycle for the periodic pressure Poisson.

Assembles the ported operators (RB-GS smoother, averaging restriction, trilinear prolongation, mean removal) into a correction-scheme V-cycle for Lap(phi)=d on a periodic staggered grid. Coarse operators are the rediscretized constant-coefficient Laplacian at the level spacing (A = -Lap = (6 phi - sum)/h^2). This replaces the slow plain RB-GS pressure solve in FlowReference. Single GPU (periodic ghost wrap per level). Any Kokkos backend.
