name: wai-quantum for Python, release wheels

# On a tag wai-quantum-cli-v<version> (the command line's release), builds the Python
# package's wheels (wai/wai-quantum-py) and attaches them to the same forge release,
# each with its SHA-256. One abi3 wheel per platform serves every Python from 3.9 on:
#   macOS      arm64 and x86_64 (the x86_64 one cross-built on the Apple-silicon runner);
#   Linux      x86_64 and arm64, manylinux2014 (glibc 2.17), linked with zig so the
#              runner's newer glibc does not leak into the wheel;
#   Windows    x86_64.
# Each wheel that runs on its runner is installed alone on Python 3.9 in a fresh venv
# and runs tests/smoke.py before it is attached. Nothing is published to a package
# index.
#
# Uploads go to the forge directly over the private network (FORGE_API), never through
# the public tunnel. A runner that is down leaves its platform's wheel missing: the
# release lists what each build attached.
