Description: Approximate Euclidean k-nearest neighbour search routines
        that operate on 'bigmemory::big.matrix' data through Annoy
        indexes created with 'RcppAnnoy'. The package builds persistent
        on-disk indexes plus sidecar metadata from streamed
        'big.matrix' rows, supports euclidean, angular, Manhattan, and
        dot-product Annoy metrics, and can either return in-memory
        results or stream neighbour indices and distances into
        destination 'bigmemory' matrices. Explicit index lifecycle
        helpers, stronger metadata validation, descriptor-aware
        file-backed workflows, and benchmark helpers are also included.
