name: Publish packages

# Non-Rust consumers cannot take a package from a subdirectory of a git repo the
# way cargo can, which is why they ended up vendoring forks instead. This gives
# them a versioned artifact to depend on so CultLib stays the only source.
#
# Rust needs nothing here: cargo git dependencies pin a CultLib revision
# directly, which is already how Ghostlight, Epiphany, CodexConnector and Odin
# consume the core stack.
#
# Tag a release to publish, for example `cultcache-ts-v0.13.6` or
# `cultnet-py-v0.1.0`. The tag's version must match the version in the package
# manifest; the workflow refuses the publish otherwise rather than shipping a
# mislabelled artifact.
