feat(interpreter): enhance result representation

Improve the handling of expression evaluation results in the interpreter by attempting to use `__repr__`, falling back to `str`, and finally relying on a basic string conversion if necessary. This approach ensures more robust and informative output for various types of objects, addressing potential issues where the direct conversion to a string might fail or not provide sufficiently detailed information.

This enhancement makes the interpreter more user-friendly and resilient, delivering clearer feedback to users about the outcomes of their operations and making debugging more straightforward.
