Detailed Description

Localize the ~1% sdflow-collocated vs AMR converged-k difference: run both on the SAME
registration-matched SC sphere and compare the converged velocity fields cell-by-cell. Is the
difference at the cut cells (projection/openness) or in the bulk (base operator)?

sdflow and AMR each init Kokkos and one finalizes it, so they cannot share a process — each engine
runs in its own subprocess (mode 'sdflow'/'amr') and writes its u-field to .npy; mode 'compare'
(default) spawns both and diffs. sdflow cell (i,j,k) centre=(i,j,k); AMR origin=-0.5 puts leaf
(i,j,k) centre at (i,j,k), so the grids coincide.
