Add assess_linked_issue_consistency to review_proofs: reviewer final
reports must report a "Linked issue status" that matches the issue(s)
the selected PR was live-verified to link this session. Without live
proof the field may only say "not verified in this session"; with
proof, every linked issue must be named, and any other "Issue #N"
mention anywhere in the report fails as stale leakage from a previous
PR (the PR #280 / Issue #260-vs-#275 incident). Missing field fails
closed. Tests cover correct linked issue, stale previous issue in both
the status field and diagnostics, missing proof, unverified wording,
multiple linked issues, and PR-number mentions not being mistaken for
issue mentions.
