Cython + setuptools C++ extension using jemalloc and xsimd (both built from source in CIBW_BEFORE_ALL, inherited from upstream's own pyproject.toml). tabmat's dense/sparse helpers already fall back to scalar code under XSIMD_NO_SUPPORTED_ARCHITECTURE, which covers riscv64 since xsimd has no vector-extension backend enabled by default there.

Flipped to published with the real PR and current version.
