name: Publish Python Bootstrap

# Builds and publishes the pure-Python `a3s-code` bootstrap shim to PyPI.
# The shim is tiny (no native code) so it sails under PyPI's per-project
# size cap. On first `import a3s_code` it downloads the matching native
# wheel for the user's platform from this repo's GitHub Releases.
