forge-bot c3a0259e95 다양화: 530개 online/batch 프로그램을 모듈별 고유 실업무 로직으로 재작성
- 템플릿 클론(정규화 후 0줄 상이) → 전 코퍼스 530/530 고유 바디
- 11개 모듈(mg/au/ac/rc/vl/st/py/lg/mm/cm/cl) 각 파일이 distinct한
  매입·대사·정산·수수료·지급·원장·마감·마스터·정합성·전문게이트웨이·공통 업무
- TxCore(ATMI 유사) + ECPG(EXEC SQL) 관용구, 프레임워크/헤더/DBIO API/파일ID·경로 유지
- 전체 docker make -j4 = EXIT 0, 958 오브젝트, 데모 바이너리 링크
- inventory.json loc 실측 갱신
