Pull Request Overview

This PR fixes type hinting inconsistencies for the locals_max_length and locals_max_string parameters in the traceback module. The parameters were documented to accept None values but were typed as int, causing type checker errors when None was passed.

• Updated type annotations from int to Optional[int] for both parameters across multiple functions
• Resolves mypy/type checker errors when passing None to these parameters
