feat(meta-eval): backport the judge gate to 0.203 (0.203.3)

GTM pins agent-runtime 0.291.0 and agent-knowledge 18.0.0, whose agent-eval peer windows end below 0.204. The judge gate shipped in 0.210/0.211 (#961, #963), so GTM's adoption (#1445) broke its peer-floor ship check and was reverted (#1448). No agent-runtime or agent-knowledge release on GTM's interface-2 cohort admits agent-eval 0.211.
