feat(execution,obs): 호가단위 스냅(dcy-030/#28) + 운영 관측성(dcy-029/#29) + REL-007 환류

dcy-030 (issue #28, P0 체결 복구):
- REQ-083 KRX 호가단위(tick) 순수 유틸 (domain/pricing.py)
- REQ-070 CHG: 슬리피지 실효가 호가단위 스냅 — 상한 준수(매수 floor/매도 ceil)
  + band<1tick 하한/상한 보장 + 부동소수 epsilon 가드. 147700→148400/54500→54700.
- BAT-044 release-candidate

dcy-029 (issue #29, 운영 관측성):
- REQ-084 구조화 로깅 기반 (runtime/logging_setup.py): ISO8601 KST·레벨·Loki JSON
  ·correlation id(slot_id)
- REQ-085 주문 결과 로깅 (event=order_submit|fill|reject)
- REQ-087 거부 ERROR 가시성 (조용한 롤백 제거)
- REQ-086 청산 reason+actor 동반 노출 (안전망/전략 구분, 신규 필드 없음)
- REQ-088 운영 조회 CLI report (application/operator_report.py, 보유·오늘 체결
  ·실현 PnL net·대기, direct-DB)
- REQ-089 운영자 런북 docs/operations.md
- REQ-090 baseline 정합 (runtime-flows·project-structure·interface-contract)
- BAT-045(P0)·BAT-046(P1) release-candidate

REL-007: confirmed → feedback-captured (운영 인스턴스 라이브 검증 + #28/#29 환류
정규화). BAT-037~041 released.

검증: 537 passed, 47 skipped, 회귀 0, ruff clean.
