Automated Action d993db2f17 Implement subtasks functionality for todo system
- Add parent_id field to Todo model with self-referential foreign key
- Add parent/children relationships and is_subtask property
- Update TodoCreate/TodoUpdate schemas to include parent_id
- Add subtasks list to Todo schema and create SubtaskCreate schema
- Enhance get_todos CRUD function with parent_id filtering
- Add subtask-specific CRUD functions: get_subtasks, create_subtask, move_subtask
- Add API endpoints for subtask management
- Create migration for adding parent_id column
- Update imports and fix circular dependencies
- Ensure proper cycle prevention and validation

Features added:
- GET /todos/{todo_id}/subtasks - Get all subtasks for a todo
- POST /todos/{todo_id}/subtasks - Create a new subtask
- PUT /subtasks/{subtask_id}/move - Move subtask or convert to main todo
- Query parameter parent_id for filtering by parent
- Query parameter include_subtasks for excluding subtasks from main list
