[askpt]

This PR

This pull request updates the pull request title validation workflow to provide clearer feedback to contributors when their PR titles do not meet the Conventional Commits specification. It adds automated commenting for failed title checks and cleans up comments when the issue is resolved.

Enhancements to PR title validation workflow:

• Added the marocchino/sticky-pull-request-comment GitHub Action to automatically comment with a helpful error message if the PR title does not follow the Conventional Commits specification, including details from the linter output.
• Configured the workflow to delete the error comment once the PR title is corrected and passes validation, keeping the discussion clean.
