다양화 Wave2: dbio 289 + common 120 고유화 + 프로그램 206개 EXEC SQL 심화

- dbio io(289): fetch/touch/total 시그니처 유지, SQL 바디를 JOIN/집계/커서/
  upsert/DELETE 등 구조로 고유화 → 289/289 고유
- common cu(120): 유틸 시그니처 유지, Luhn/CRC/Zeller/BIN레인지/amortization/
  netting 등 실 알고리즘으로 고유화 → 120/120 고유
- 심화: 실제 EXEC SQL 없던 프로그램에 SELECT/INSERT/UPDATE/커서+tx 추가
  → online+batch 530/530 전부 실제 SQL 보유
- 전 코퍼스 프로그램 939/939 고유, 전체 docker make -j4 = EXIT 0, 958 오브젝트
- 임시 생성기 제거, inventory.json loc 실측 갱신
