The body-scan fallback (includes("APPROVE") etc.) would misclassify verdicts
when the reviewer mentioned a keyword in context without it being the actual
verdict — e.g. "this does not yet merit APPROVE". Replaced with a
line-anchored regex that only matches "Verdict: X" lines, and expanded the
primary regex to also catch bold/italic formatted verdicts like **Verdict: APPROVE**.
UNAVAILABLE is now the honest fallback when no structured verdict is found,
triggering a retry rather than silently misclassifying.
