feat(engine): ComponentRegistry, EcsCore, signature 갱신 및 cleanup flow…

[SilverSupplier]

… 구현 (#8)

Summary

• ComponentRegistry: 컴포넌트 타입별 고유 ID 부여 및 PackedComponentStorage 중앙 관리
• EcsCore: EntityRegistry + ComponentRegistry 통합 코어
  • addComponent/removeComponent 시 entity Signature 자동 갱신
  • destroyEntity 시 notifyEntityDestroyed로 등록된 모든 storage cleanup
• EcsCoreTests: 생명주기, 컴포넌트 추가/제거, cleanup flow, 인덱스 재사용 검증

Related Issue

• Closes Task-Implement ComponentRegistry, Signature updates, and EcsCore cleanup flow #8

Area

• Engine

Architecture Check

• I kept the dependency direction application -> domain -> engine.
• I did not add Qt UI code to src/domain.
• I did not add domain or application dependencies to src/engine.
• I used src/ as the include root.

Verification

• cmake --preset windows-debug
• cmake --build --preset build-debug
• ctest --preset test-debug
• Not run (reason below)

로컬 환경의 PATH에 cmake가 없어 직접 실행 불가. CI pipeline에서 검증됨.

Risks / Follow-up

• WorldQuery(Task-Implement WorldQuery facade for ECS reads #9) 구현 시 EntityRegistry::eachAlive() 추가 예정
