X Title: support | operation between typing.Union and strings by elmjag · Pull Request #6983 · RustPython/RustPython

Description: Adds support for performing '|' operation between Union objects and strings, e.g. forward type references. For example following code: from typing import Union U1 = Union[int, str] U1 | "float" The result of the operation above becomes: int | str | ForwardRef('float') Summary by CodeRabbit Refactor Union-type combination now follows a typing-based path with a fast path for common cases, improving correctness and error handling. Internal typing helper consolidated into a shared typing call to simplify type-variable and typing operations. Reduced public exposure of an internal unionability helper while preserving outward union behavior.
