* Inject PR title and body into reviewer context The reviewer agent previously received the PR url, number, and SHAs but not the PR title or description, so it sometimes missed the original intent of the PR. Fetch the title/body fresh from the GitHub API on every run (never cached) so edits to the title/description are reflected on re-reviews, and inject them into the first-review, re-review, and finding-reply contexts as an untrusted-data block (author-controlled text, guarded against prompt injection). * Harden PR overview escaping against whitespace-padded closing tags
