name: Post-merge

# Runs on every push to master (after CI workflow merges a PR).
# Consolidated into 2 jobs (from 7) to reduce runner overhead:
#   detect-and-configure ──→ release-and-maintain
#
# Job 1: detect release commit, validate commit msg, configure repo
#        (branch protection, labels).
# Job 2: release + publish + sync-wiki + vikunja + badges.
#        Individual steps are conditional on job 1 outputs.
#
# The badges step always runs (even on release commits) so version
# badge picks up the new __version__. It runs last so it sees the
# new version if release created one.
#
# When release creates a "release: vX.Y.Z" commit and tag, the publish
# step builds and publishes the package to the Gitea PyPI registry.
# The release commit's post-merge run still updates badges. Other
# steps (sync-wiki, vikunja) skip on release commits.
