- shared/base_repository.py 新增 batch_delete_r（返回 R，等价原 base_model 语义） - 20 个模块删除函数从 Model.batch_delete_r 改为 x_repo.batch_delete_r - shared/base_model.py 移除 classmethod（get_by_id/get_by_ids/get_all_active/exists/batch_delete_r），只留字段 + to_dict - 清理 base_model 多余 imports - 实测 dept 删除、批量删除及多模块读接口正常 Co-Authored-By: Claude <noreply@anthropic.com>
