3. Detect components built on top of other components
4. Suggest flattening strategies
5. Create refactoring plan

User: "Flatten component hierarchies in this codebase"

The skill will:
1. Identify components with hierarchy issues
2. Analyze orphaned classes
3. Suggest consolidation or splitting strategies
4. Create refactoring plan
5. Estimate effort

User: "Analyze component structure for hierarchy issues"

The skill will:
1. Map component namespace structure
