docs(discovery): dcy-027 모든 OQ Answered — 중장기 슬롯 운영 결정 완료

OQ-1: (a′) 기존 슬롯 도메인 유지 + 운영 프로파일/규칙 추가 (PositionBook 불필요)
OQ-2: safety_sell_enabled=false → 코어 손절매 루틴 없음, 전략 모듈 전적 책임
OQ-3: per-instance watchdog_timeout_sec 연장 (1800s 이상 권장), 알림은 후속 Discovery
OQ-4: 중장기 전략 폴링 주기 최소 1분·최대 10분

feat(bat-041): REQ-076/077/078 — watchdog timeout TOML + 중장기 운영 프로파일 + baseline
