Conversation
Use references to the fine-to-coarse mapping while the newly created coarsened view owns it, then copy that mapping only once into composedMapping for flattening. This removes avoidable O(n) vector copies during each ParallelLeidenView coarsening handoff without changing ownership or partition semantics.
