// Manual smoke test for the configured guardrail LLM judge against a live
// provider. Gated by a build tag so it never runs in CI. Invoke with:
//
//	go test -tags=judgesmoke -run TestJudgeSmokeManual -count=1 -v ./internal/gateway
//
// Requires ~/.defenseclaw/config.yaml with guardrail.judge.enabled: true and
// ~/.defenseclaw/.env containing DEFENSECLAW_LLM_KEY (or whichever
// llm.api_key_env is configured).
