Shrimp Task Manager

### Existing Task References #### Completed Tasks {completedTasks} #### Incomplete Tasks {unfinishedTasks} #### Task Adjustment Principles 1. **Completed Task Protection** - Completed tasks cannot be modified or deleted 2. **Incomplete Task Adjustability** - Incomplete tasks can be modified based on new requirements 3. **Task ID Consistency** - Must use original IDs when referencing existing tasks 4. **Dependency Relationship Integrity** - Avoid circular dependencies, do not depend on tasks marked for removal 5. **Task Continuity** - New tasks should form a coherent whole with existing tasks
