Implement GitHub PR Issue Checker Workflow

[smog-root]

FIX #1264

Usage:

1. When a pull request is created or edited, the workflow automatically triggers.

2. The workflow checks for:

• A non-empty PR description.
• A valid issue reference format (FIX #<issue-number> or FEAT, or DOC #NEW).

3. If either check fails, the PR will be marked as failing, and the author will receive clear error messages in the PR comments.
4. If all checks pass, a confirmation message will indicate that the PR is valid.

Note: Kindly add all the labels added to the issue, to this PR!
