Small pure-Rust PyO3/maturin string-case-conversion library (heck crate). abi3-py37, no native deps beyond rustup; validated locally by building the checkout with maturin and by rehearsing the full cibuildwheel job against manylinux_2_39_aarch64.

pyproject.toml pins maturin<0.13, which has no riscv64 wheel on PyPI and fails to build from sdist because its own bootstrap assumes an ambient setuptools that Python 3.12+ no longer seeds into a build isolation venv. Install a current maturin (which builds this tree unmodified, confirmed locally) and skip isolation to bypass the pin. Verified with a full cibuildwheel rehearsal against manylinux_2_39_aarch64: build, licence check and pytest all pass.
