Subject: [PATCH] lzallright: add build-lzallright.yml for riscv64 wheels

Rust/PyO3 (maturin) LZO binding: single cp38-abi3 wheel built on cp39
(the riscv64 image's floor) covers cp39-cp314, with a separate cp314t
wheel for the free-threaded build (image ships no cp313t, so it
substitutes for upstream's cp313-cp313t). libstdc++-static (CRB-only)
is installed alongside rustup for lzokay-sys's vendored C++ build.
