TenRSo 0.1.0-rc.1 Released — A Rust-Native Tensor Stack: Generalized Contraction, Decompositions, and Out-of-Core, the Last Step Before Stable

TenRSo is a production-grade, Rust-native tensor computing stack — generalized contraction plus a cost-based planner, sparse/low-rank mixed execution, CP/Tucker/TT decompositions, and out-of-core processing. This release candidate adds masked einsum, executor element-wise ops, TT-SVD gradients, and CP regularization as we approach our first stable cut.
