Detailed Description

flow — assembled single-GPU periodic Navier-Stokes step on Kokkos fields.

Composes the ported operators into a Chorin projection step on a staggered MAC grid (periodic box, ghost width 2): explicit Koren-TVD advection (optional) + backward-Euler implicit diffusion (RB-GS) -> divergence -> pressure Poisson (RB-GS + mean removal) -> projection correction. Divided convention (operator (1/dt)I - nu*Lap). Single GPU: the "halo" is a periodic ghost wrap. This is the cfd analog of the packing demStep — it wires the validated kernels into a runnable solver.
