feat(memos): 자료로 보내기 P2 — 메모→문서 26B 문서화 워커

memo_draft_worker(interval 2분): promote 가 찍은 source_metadata.needs_draft=true
문서를 26B(call_primary, acquire_mlx_gate BACKGROUND)로 구조화 마크다운(md_content)
생성. content_origin='ai_drafted'+md_draft_status='draft'(mig212 제약 준수), 원본은
extracted_text 보존. promote 엔드포인트에 needs_draft 마커 + main.py add_job.
큐 enum/컨슈머 무변경(derived-worker 패턴) = 저위험.
