Add strategy pattern architecture for BOM module processing

- Add IModuleProcessor interface defining the processor contract
- Implement cProcessor_AppendOnly strategy for modifying existing BOM rows
- Implement cProcessor_CloneNew strategy for creating new BOM rows
- Add mProcessorFactory module for creating processor instances
- Add mSpecAdditionManager module for coordinating spec addition operations
- Enhance test suite with business logic layer and pipeline integration tests

This implements the Strategy pattern to allow flexible BOM modification behaviors while maintaining clean separation of concerns.

+' 模块职责: 通用克隆新增策略。适用于弹性元件等需要完全独立成行的规格。
+' 逻辑描述: 找到第一个匹配的母版行，克隆它并赋予纯粹的新规格条件。
