fix: align reviewer eval with published findings (upstream #1713) (#201)

* fix: align reviewer eval with published findings (#1713) * fix: make reviewer eval reflect published findings Serialize and deduplicate finding persistence, align review calibration around the final six-finding publication, and make judge matching order-independent and auditable. * fix: honor reviewer eval limits Forward configured caps into publication snapshots and keep recall-at-cap bounded for diagnostic all-findings runs. (cherry picked from commit 71e3b8183882bcc42e318f3f220c291617ebcb67) Co-authored-by: Johannes du Plessis <johannes@langchain.dev> * Empty commit to trigger CI --------- Co-authored-by: Johannes du Plessis <johannes@langchain.dev>
