feat(classic): add utility components for agent capabilities

Add 6 new utility components to expand agent functionality:

- ArchiveHandlerComponent: ZIP/TAR archive operations (create, extract, list)
- ClipboardComponent: In-memory clipboard for copy/paste operations
- DataProcessorComponent: CSV/JSON data manipulation and analysis
- HTTPClientComponent: HTTP requests (GET, POST, PUT, DELETE)
- MathUtilsComponent: Mathematical calculations and statistics
- TextUtilsComponent: Text processing (regex, diff, encoding, hashing)

All components follow the forge component pattern with:
- CommandProvider for exposing commands
- DirectiveProvider for resources/best practices
- Comprehensive parameter validation
