feat(slot): BAT-030 — 자산 중심 cutover 완성 (dcy-020 BAT-δ, REQ-056·057·062·064·065)

M1 literal inactive 전면화: SlotState 5-state(idle/closed 별칭 제거),
마이그레이션 010(CHECK 교체+행 rewrite), ops_checks 를 transition_log 기반 재작성.
M2 집행 매도 수량 브로커 정본(D3): dispatch 매도 qty=broker hldg_qty,
미러 fallback 없음, 브로커 0 → skip+WARN, 리스트 기반 dispatch(head-block 방지).
M3 컬럼 drop + legacy pool 제거: 마이그레이션 011(trading_date·entry_count DROP),
repo 계약 instance 스코프 개편(집행 큐 포함), preallocation 폐기(데몬 7스레드),
admission 자산 중심 단일 경로(slot_id 정본), capacity 재정의(available=M−active),
daily_symbol_entries 코드 경로 제거.
M4 cutover 도구(D1·D4): trex-core-cutover(전체 rebuild, preflight/브로커 carry-over/
--allow-unmapped/--promote-unique/dry-run) + PG 리허설 테스트 8건.
M5 baseline 마감: data-model/runtime-flows/project-structure/interface-contract
자산 중심 최종 갱신 + run-trex-core-daemon 스킬 정합.

검증: 단위 367 passed + ruff clean; PG-gated 29 passed(010/011 round-trip·드리프트
가드·cutover 리허설); RabbitMQ 21 passed; run-the-app e2e(test DB+실 MQ, M=1):
reconcile 슬롯 생성→slot_id 매수→dedup→capacity_full→fill→already_active→
매도→inactive(자산 바인딩 보존)→영구 슬롯 재활성 전 구간 green.
실 cutover 는 운영자 실행(REL 단계, D4).
