- Add special handling for target_level=0 to return only total part count and hierarchy levels - Use ListDisplayedComponents() for total component counting (same as GetModelStatus) - Use SafeCalculateAssemblyLevels() for hierarchy level counting (same as GetModelStatus) - Remove unnecessary recursive counting methods (CountTotalParts, CountMaxLevels) - Improve performance by avoiding full hierarchy tree construction when only counts are needed - Ensure consistency with existing model status API results 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
