name: Publish packages

# Publishes one public @ekklesia/* package train (ADR 0053, docs/development/releases.md) to the
# npm registry: exactly the artifacts this run's package-release gate proves, and nothing else.
#
# Only ever started by hand, on `main`, by someone with write access to this repository: no pull
# request or push can start it. It needs the version-set commit of a release (`version` must equal
# the platform version there), and the repository secret EKKLESIA_PACKAGES_PUBLISH_TOKEN, a token of
# the dedicated publisher account with only the `write:package` scope. Packages are publicly
# readable (ADR 0054); publishing is what this protects.
