feat(api): sync test API (serve) + opt-in LLM correction + cloudflared tunnel
- api/: FastAPI app, X-API-Key 인증(미설정 시 임시키), 엔진 load-once 풀
(+transcribe lock), POST /v1/transcribe(multipart, 동기), /health, /v1/system,
/v1/models. 업로드 임시파일 finally 삭제(프라이버시).
- postprocess/: llm.correct(scripts/llm_correct.py 승격; opt-in·allowlist·감사로그·재시도)
+ rules.normalize(EmbeddingGemma 등 정규화).
- results/formats.py: txt/srt/vtt. connectivity/tunnel.py: cloudflared quick tunnel(Colab).
- cli serve: uvicorn 단일워커 + --tunnel cloudflare; config llm_* 필드;
pyproject api/queue extra 분리(+python-multipart, dev httpx).
검증: 22 단위테스트(API TestClient·formats·postprocess) + 실서버 e2e
(/health·auth 401·실제 전사(JFK)·SRT·임시파일 삭제). KO 품질은 turbo/large-v3 필요(tiny는 한국어 degenerate).
