✅ Fixed the failing check by updating the PR title to follow the conventional commit format. The PR title now includes the "feat:" prefix to indicate this is a feature addition.

The check was failing because the repository uses semantic-pull-request to validate PR titles according to the Conventional Commits specification.

The PR should now pass all checks on the next run.
