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.
