This adds a partition-addressable precomputed artifact format that lets external vector backends hand Lance encoded partition data without changing the final on-disk index format.
It also changes the Python
accelerator="cuvs"path to delegate to the externallance_cuvspackage at runtime, keeping CUDA/cuVS implementation details out of the main tree while preserving the existing Lance finalization flow.
