pytokens publishes mypyc-compiled wheels for common platforms but not riscv64. Mirrors upstream's wheels.yml build_wheels job narrowed to manylinux_riscv64, plus the pytest suite tox runs (upstream's cibuildwheel run does not test its wheels). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Adds a riscv64 wheel build for pytokens 0.4.1.
pytokens is a fast, spec-compliant Python tokenizer (used by black). It publishes
mypyc-compiled per-interpreter wheels for x86_64/aarch64/macOS/Windows but nothing
for riscv64, so
pip install pytokensthere falls back to the pure-Pythonpy3-none-anywheel.The workflow mirrors upstream's
wheels.ymlbuild_wheelsjob, narrowed tomanylinux_riscv64. Upstream's[tool.cibuildwheel]table in
pyproject.tomlsuppliesbuild-frontend = "build"and theMYPYC_*env,so only the riscv64 image needs overriding.
setup.pyenables mypyc by default onCPython, so no opt-in env var is needed.
Upstream does not run tests through cibuildwheel, so the test step here runs the same
pytestsuite their tox envs do, preceded by an assert thatpytokens.__file__is a.so— a compiled-wheel check, since a pure-Python fallback would still carry theriscv64 platform tag.
Matrix is per-interpreter
