+// Design decisions:
+//   - PR titles use "chore(deps):" prefix to satisfy commitlint and avoid
+//     triggering a semantic-release version bump on merge.
+//   - Go and frontend (pnpm) dependency updates are grouped separately to keep
+//     PRs reviewable and CI matrix manageable.
+//   - GitHub Actions are tracked and grouped into a single PR.
+//   - The custom beep fork (TheCodeOfCaleb/beep) is excluded from updates.
+//   - Go tool directives (templ, sqlc, lefthook) are tracked automatically.
