Greptile Summary

This PR adds a new GitHub Actions workflow (.github/workflows/lint-pr-title.yml) to enforce the conventional commits format on PR titles using amannn/action-semantic-pull-request@v6, matching the setup in authkit-nextjs.

• Triggers on pull_request_target with opened, edited, and synchronize event types; uses pull_request_target so the token is available even for fork-originated PRs.
• The action is pinned to a full commit SHA (48f256284bd46cdaab1048c3721360e808335d50) for supply-chain safety, and permissions are scoped to pull-requests: read only — consistent with the minimal-permission pattern used in the existing CI workflow.

Confidence Score: 5/5

Safe to merge — adds a read-only linting workflow with no checkout step and minimal token permissions.

The workflow is a simple, self-contained addition. The action is SHA-pinned, the GITHUB_TOKEN is restricted to pull-requests: read, and no PR code is ever checked out or executed. No existing functionality is touched.

No files require special attention.
