lint-pr-title.yml

name: Lint PR title

# Rejects PR titles that don't follow Conventional Commits format. The
# title is what release-please reads (under squash-merge) to compute the
# next version bump, so a wrong/missing prefix would silently miss a
# release. This check turns that silent failure into a visible block.
