Phase 1: 실동작 Enduro/X + PostgreSQL XA 매입 슬라이스

- Enduro/X 7.0.12 소스빌드 이미지(-DENABLE_POSTGRES=ON, libndrxxaecpg XA 스위치)
- docker-compose: postgres(max_prepared_transactions=100) + endurox app
- ECPG XA 서비스 3종: ACQUIRE→RECONCILE→SETTLE (tpservice + EXEC SQL)
- 클라이언트 tpbegin/tpcall체인/tpcommit → tmsrv 2PC(prepare/commit) 원자 커밋
- 검증: 서비스 AVAIL, 커밋 row(status=S) psql 확인, 롤백 시 무잔존, pg_prepared_xacts=0
- 규명된 런타임 요건: sysctl fs.mqueue.*, ulimit msgqueue/nofile, XA open-str JSON
- docs/architecture.md, README, service-catalog 설계
