feat: Unified registry and major code cleanup by ChatGPT5

- Unified Box Registry: Replaced 600+ line match statement with clean factory pattern
- Code cleanup: Removed unused imports, variables, and dead code
- Import fixes: Fixed RangeBox, NullBox, MapBox imports
- Transport Debug: Added Debug trait implementation for Transport interface
- WASM build: Successfully tested with wasm_playground preset ready for integration
- Performance: Build time stable, WASM package generated successfully (1.89MB)

This commit represents a major architectural improvement with the unified registry
system now fully operational, reducing code duplication and improving maintainability.
