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 life cycle helpers, stronger metadata
    validation, descriptor-aware file-backed workflows, and benchmark helpers
    are also included.
