Detailed Description

template<int Dim, unsigned Bits = (Dim == 2 ? 32u : (Dim == 3 ? 21u : 16u))>
struct peclet::amr::DistributedOctree< Dim, Bits >::GatherHaloTopology

Flattened, value-only topology for the face-neighbour gather, established ONCE: the per-matvec exchange then moves only double values (no coords, no locateGlobal) over a fixed graph — the octree analogue of GridHaloTopology::flatten().

A device DistributedGatherHalo mirrors only the compact send/recv buffers across MPI (à la grid_halo.hpp); the field stays on the device.
