Module copy_metadata 

Copy metadata (DPS / DPV / groups, optionally DPG) from a donor TRX onto a target TRX whose streamlines and vertices already match.

Unlike concatenate_any_trx and subset_streamlines, this operation does not touch positions, offsets, or the header — it only grafts named arrays from the source onto the target’s metadata HashMaps.
