X Title: Use PyStrRef for TypeAliasType name by walker84837 · Pull Request #6203 · RustPython/RustPython

Description: This MR changes TypeAliasType so that it uses a PyStrRef object for its name field instead of a PyObjectRef. Previously, the name field was a PyObjectRef. Although PyObjectRef is flexible, using a more specific type, like PyStrRef, improves transparency and type safety. Changes include: As mentioned, updating TypeAliasType.name from PyObjectRef to PyStrRef. Changing TypeAliasType::new() and __name__ getter to handle PyStrRef. Adding small type checks in: vm/src/frame.rs vm/src/stdlib/typing.rs to enforce that the TypeAliasType name is a string. Since the type of name is now a PyStrRef, the repr_str implementation for TypeAliasType was simplified by using PyStrRef::as_str() directly. Summary by CodeRabbit Bug Fixes Strengthened validation for TypeAliasType names so non-string names now produce a clear "TypeAliasType name must be a string" error. Improved consistency of TypeAliasType construction and string representation, reducing confusion when inspecting or creating type aliases.
