Enforce PR template compliance and require related issue/discussion reference #4227

Task Summary

Many pull requests are not following the PR template well, especially the "Any related issues, documentation, discussions?" section. In multiple PRs, there is no linked issue/discussion (e.g., #1234), which makes review and traceability harder.

Why this is a bad practice

• It weakens traceability: reviewers cannot easily connect code changes to the original problem statement or decision context.
• It slows down review: missing context forces reviewers/maintainers to ask follow-up questions and increases review cycle time.
• It hurts project hygiene: release notes, changelog curation, and future maintenance become harder without issue linkage.
• It reduces accountability: unclear ownership/scope makes regressions and follow-up fixes harder to track.
