Detailed Description

DistributionMapping: maps each box (by global index) to its owning MPI rank.

SEPARATE from BoxArray (AMReX convention): boxes can be redistributed without rebuilding the decomposition. The (nboxes, nranks) ctor yields a round-robin; balanced strategies (Z-order SFC, knapsack) live in parallel/load_balance.hpp and build a DistributionMapping from an explicit rank vector. REPLICATED metadata: every rank knows the full assignment (key to the distributed fill_boundary / parallel_copy paths that enumerate the same jobs on all ranks).
