Subject: [PATCH] ci: validate PR titles against Conventional Commits

Release Please only recognizes Conventional Commit prefixes (feat:, fix:,
...). PRs merged with other conventions (gitmoji, free-form) are silently
skipped, shipping changes with no version bump or changelog entry (see
#707/#708). Fail such PRs early via amannn/action-semantic-pull-request.

+# Release Please derives version bumps and the changelog from Conventional
+# Commit prefixes (feat:, fix:, ...). PRs whose title/commits use other
+# conventions (e.g. gitmoji) are silently ignored, so their changes ship
+# without a version bump or a changelog entry. This check fails a PR whose
+# title is not a valid Conventional Commit so the release stays automated.
