Subject: [PATCH] test(compiler): add native scalar property diagnostic test
 for namespaced class names

- Add test case for namespaced class name escaping in C++ string generation
- Verify proper error message display for type mismatch in namespaced properties
- Test native scalar property assignments with configuration arrays
- Validate TypeError handling for invalid type assignments in namespaced context

fix(compiler): ensure namespaced class names are properly escaped in property type checks

- Update genCharPtr call with escape parameter set to true
- Fix object property type check display name generation for namespaced classes
- Maintain backward compatibility with existing property access patterns
