Description by Korbit AI

What change is being made?

Add comprehensive enhancements and new features to the current_code_codebase.py module within the analyzers directory, including improved logging, error handling, and documentation, while introducing a test suite for validation.

Why are these changes being made?

These changes aim to create a more self-contained module with reduced dependencies, enhanced error detection and logging, and more robust programmatic interfaces via detailed documentation and type annotations, addressing the need for improved stability and maintainability of the codebase analysis and management tools. Furthermore, the introduction of a dedicated test suite ensures reliability and correctness of the added functionalities.

✅ Fixed the failing pre-commit check in this commit. The issue was related to TRY401 linting errors in the analyzer.py file, where exception objects were redundantly included in logging.exception calls. I've removed these redundant exception objects from all the logging.exception calls in the file.
