feat: 젬 이상상태 및 수치형 보정 확장

- SkillGemData와 SkillLoadoutEntry를 확장해 자기 강화/적중 이상상태와 피해·회복·보호막·위협 배율을 해석하도록 정리
- SkillController와 SkillEffect 경로를 보강해 cast start 이상상태, on-hit 이상상태, 반복 시전, 출력 보정이 실제 효과에 반영되도록 연결
- 강인함/약화 테스트 젬과 자기강화/적중이상/상태복합 프리셋, 디버그 메뉴를 추가해 젬 조합 검증 경로를 보강
- 런타임에서 약화 디버프 적용, 강인함+약화 동시 적용, 파쇄/수호/도전자 보정값 해석을 확인
