Sparse tensor support — COO, CSR, CSC formats.

703 lines. SparseCOO<T> (coordinate format: indices + values + shape) with from_dense, to_dense, nnz, density, add/mul (sparse×sparse and sparse×dense), matmul (spmm sparse × dense → dense), coalesce (sort + dedup), and transpose. SparseFormat enum tags COO/CSR/CSC variants.
