feat(E6a): 다음 막 진행·적 스케일 — 멀티 act 런

보스 클리어 시 즉시 종료 대신 다음 막으로, 최종 막 보스에서 런 클리어.

- Floor를 막 카운터(1..ACT_COUNT=3)로 재정의, RunLength=ACT_COUNT
- StartCombat: 적을 막 배율(mult=1+(Floor-1)*0.6)로 스케일(maxHp·의도값, 새 테이블)
- CheckCombatEnd 보스 승리: Floor<RunLength면 다음 막(같은 맵 재사용·CurrentNodeId 리셋·ShowMap), 최종 막이면 '런 클리어!'
- HP/골드/덱/유물 막 간 유지(기존 영속), combatStart 유물 전투마다 재적용
- RenderRun HUD 라벨 '층'→'막'
- 메이커 Play 검증: 보스 120→192→264 스케일, 막 1→2→3, 3막 클리어, 영속 유지
- 제외: E6b 저장/불러오기(미진행)
