Detailed Description

Utility for distributed or local row permutation/transfer of arrays.

Encapsulates the common pattern: given a partition assignment (or forward map) for a set of entities, compute new global indices and transfer array rows to their target ranks. Supports both distributed (MPI push) and local-only (in-place permutation) paths.
