## 並行執行計劃

### Wave 1 (可完全並行)
```
Terminal 1: Task 0 (init)      → 30min
Terminal 2: (等待 Task 0)
```

### Wave 2 (可完全並行)
```
Terminal 1: Task 1 (domain)         → 2h
Terminal 2: Task 2 (infrastructure)  → 1h
Terminal 3: Task 8 (cli)             → 30min
```

### Wave 3 (可部分並行)
```
Terminal 1: Task 3 (repository)      → 1h (依賴 Task 1)
Terminal 2: Task 4 (provider)         → 30min (依賴 Task 1)
Terminal 3: Task 6 (adapter)          → 30min (依賴 Task 1)
Terminal 4: (等待 Task 3)
```

### Wave 4 (可部分並行)
```
Terminal 1: Task 5 (usecase)          → 2h (依賴 Task 3)
Terminal 2: (等待 Task 5)
```

### Wave 5 (序列)
```
Task 7 (internal)                     → 4h
Task 9 (cleanup)                      → 4h
```

**總時間估計**:
- 完全序列: ~15h
- 並行執行: ~9h
- 節省: ~40%
