# Create an annotated version tag carrying auto-generated release notes (git-cliff)
# and push it. The tag push triggers .gitea/workflows/release.yml, which builds the
# image and publishes a Gitea Release whose body is this tag's message. Notes come
# entirely from Conventional Commits — no hand-written message required.
#
# git-cliff's --latest needs the tag to exist to scope the notes, so we create a
# throwaway lightweight tag, generate the notes, replace it with an annotated tag,
# then push. --cleanup=verbatim keeps the markdown "###" group headers (git's
# default cleanup would strip lines starting with "#").
