Implement SetWorkingDirectory method with OTK API integration:
- GetCurrentDirectory() to retrieve current path
- ChangeDirectory() to switch working directory
- Intelligent comparison: only changes if target differs from current
- Path normalization for Windows (case-insensitive, backslash handling)
- Comprehensive error handling with detailed result structure
Also includes minor code cleanup in CreoManager.cpp formatting.
