Parallelize positions (12s→1.5s) + add scan --all-chains (11 chains in 1s)

positions: tokio::JoinSet scans all 11 chains concurrently.
  Before: 12 seconds (sequential)
  After: 1.5 seconds (parallel)

scan --all-chains: new flag for parallel multi-chain exploit detection.
  Scans all 11 chains simultaneously, returns unified JSON with
  chains array + total_alerts. Single-chain mode unchanged.

  defi scan --all-chains --once --json
  → 11 chains, 15 alerts, 1013ms

+
+## Goal
+`positions`와 `scan` 커맨드를 병렬화하여 11개 체인 동시 조회. positions 12초→1.5초, scan에 `--all-chains` 플래그 추가.
+
+## Scope
+
+### 1. positions 병렬화
+- **파일**: `crates/defi-cli/src/commands/positions.rs`
+- **변경**: 순차 for loop → `tokio::JoinSet` 병렬 실행
+- **동작**: 11개 체인 동시 multicall, 실패한 체인은 skip (에러 무시)
+- **목표**: 12초 → ~1.5초
+
+### 2. scan --all-chains
+- **파일**: `crates/defi-cli/src/commands/scan.rs`
+- **변경**: `--all-chains` 플래그 추가. 모든 체인 동시 스캔.
+- **동작**: 각 체인별 scan 결과를 병렬 수집 → 통합 JSON 출력
+- **출력**: `{ chains: [{ chain, alerts, data }...], total_alerts, scan_duration_ms }`
+
+## Constraints
+- `tokio::JoinSet` 사용 (tokio 1.x에 포함)
+- RPC 에러 시 해당 체인 skip (전체 실패 X)
+- 기존 단일 체인 동작 유지 (--all-chains 없으면 기존과 동일)
+- mantle-cli의 positions/scan은 단일 체인이라 변경 불필요
+
+## Non-Goals
+- 테이블 출력 포맷 (이번에 안 함)
+- yield scan 크로스체인 (다음에)
+- 새 프로토콜/체인 추가 (이미 108개)
+
+## Acceptance Criteria
+- [ ] `defi positions --address 0x... --json` 이 3초 이내 완료 (11체인)
+- [ ] `defi positions --address 0x... --chains ethereum,mantle --json` 필터 동작
+- [ ] RPC 실패 체인은 skip, 나머지 정상 반환
+- [ ] `defi scan --all-chains --once --json` 이 11체인 동시 스캔
+- [ ] scan 결과에 chains 배열 + total_alerts 포함
+- [ ] 기존 `defi scan --chain bnb --once --json` 동작 유지
+- [ ] CI 통과 (clippy, fmt, test, build)
