A lightweight local vector index for approximate nearest neighbor (ANN) search using the vendored 'USearch' library Vardanian (2023) <doi:10.5281/zenodo.7949416>. Provides a simple interface for adding vectors, searching for nearest neighbors, and persisting indexes to disk. Metadata filtering is performed in 'R' on the candidate set returned by the 'C++' layer.
