WIP: Phase 9.78b - Unified registry integration (import issues pending)

Progress made:
- Add unified registry call to objects.rs execute_new() method
- Initialize unified registry in runner.rs on startup
- Create global registry management in runtime/unified_registry.rs
- Add test case for unified registry validation
- Implement fallback to legacy match statement for compatibility

Current issue:
- Module import errors in runtime/unified_registry.rs preventing build
- Need to resolve box_factory module path visibility from runtime context

Next steps:
- Fix import paths for box_factory modules
- Test unified registry functionality
- Remove legacy match statement after validation

Technical details:
- execute_new() now tries unified registry first, falls back to legacy
- Registry initialized with BuiltinBoxFactory and PluginBoxFactory
- Maintains backward compatibility during transition
