# Automated Branch Cleanup
#
# Deletes remote branches that have been merged into main and are older
# than a cutoff (default 30 days). Detects both fast-forward and
# squash-merged branches via the Forgejo API.
#
# Runs on a schedule (~every 10 days) and can be triggered manually
# with a custom cutoff for testing.
