// 서포터즈 자동 빌드 워커 (v1 §3 파이프라인, v2 §7-6, §12-3). 병원 URL 하나로 근거 수집 → 데이터 → 글 생성 → 빌드·게이트 → (배포) 까지 순서대로 돈다.
// 실행 환경에 독립적이다. 로컬·GitHub Actions·Trigger.dev 태스크 어디서든 `node workers/supporters-build/run.mjs ...` 로 부른다.
//
//   node workers/supporters-build/run.mjs --clinic <id> --url <https://...> [--name 상호] [--work ~/supporters-builds/<id>]
//        [--inputs inputs.json | --from-supabase] [--brief briefs.json] [--max-posts 6] [--max-cost-usd 3]
//        [--deploy] [--build-id <supporter_builds.id>] [--from <phase>] [--skip-generate]
//
// 단계: evidence → data → inputs → briefs → generate → build → deploy → done
// 단계마다 <work>/status.json 을 쓰고, --build-id 와 SUPABASE_SERVICE_ROLE_KEY 가 있으면 supporter_builds 행을 갱신한다.
// 게이트(check.mjs)가 error 를 내면 status=gate_failed 로 멈춘다. 사람 게이트(검토·승인)는 여기서 자동화하지 않는다.
