Neon migration smoke test 3 — bot crashes on PRs with no body

[guillermoscript]

Third attempt after the GITHUB_TOKEN fix. Same crash pattern as the previous tests: PR with empty body → bot throws → no comment.

Should be detected as a duplicate of #154.

AI response: Confidence 100% — duplicate of #167. The new issue is identical to candidate #167, including the title and description, so it is unquestionably the same underlying problem. It is also explicitly described as a duplicate in the text.
