Pull Request Overview

This pull request refactors the local symbol table to use a dataclass instead of tuples, improving code maintainability and type safety. The changes eliminate the need for a separate local_var_metadata dictionary by incorporating metadata directly into the symbol table entries.

Key changes:

• Introduced LocalSymbol dataclass to encapsulate variable information
• Removed local_var_metadata parameter from function signatures throughout the codebase
• Updated all code accessing symbol table to use the new dataclass attributes
