Add pr submission information verification

The current PR submission information is not standardized, has no correlation with the issue, and has no clear classification.
A mandatory check logic needs to be added.

No file, test, or entry point is identified in the issue. First locate the repository's pull-request checks and contribution guidance, then define the required submission fields, issue correlation, and classification rules before choosing an implementation point. Done means pull requests are rejected when the required information is missing or invalid.
