Description: Computes on arrays that do not fit in memory. Vectors,
        matrices and tensors are allocated inside a memory-mapped file
        through R's ALTREP interface, backed by a patched copy of the
        'fmalloc' allocator, so available RAM becomes a speed gradient
        rather than a hard limit. Two plugin registries sit on that
        substrate: a codec registry deciding how bytes are stored, from
        lossless floating-point and sparse encodings to compressed and
        quantized blocks, and a matrix-multiply backend registry
        deciding how products are computed, defaulting to whatever
        'BLAS' the R build links against. Matrix products stream in
        bounded panels and release the pages they have consumed, so
        operands larger than memory still multiply. A registered
        backend may decline any product, in which case the default path
        answers it, so results never depend on which backend is
        selected. Also provides persistent and scratch runtimes,
        durable reference-based serialization, explicit vector
        lifecycle management, multiple runtime handles per session, and
        out-of-core reductions and principal components for
        genomics-scale matrices.
