docs(hybrid): 아키텍처 결정 가이드 재구성 — 6가지 설계 결정 지도로 확장 KO+EN

- Pod CIDR 노출 단일 주제 → 6-결정 구조(연결·토폴로지·Pod CIDR 노출·CNI·노드 인증·워크로드 노출)
- 옵션 번호 ①②③ → A/B/C 개칭(결정 번호와 충돌 방지), 결정 간 의존 관계 mermaid 추가
- DX vs VPN 판단표(터널당 1.25Gbps, DX 전용 1·10·100Gbps 등 팩트 앵커) 신설
- 허브 카드·overview 인덱스·fundamentals 참조 문구 동기화(KO+EN 8곳)
