Code Review

This pull request exposes the BaseClient class from the a2a.client package. The changes in src/a2a/client/__init__.py correctly add the import for BaseClient and include it in the __all__ list. The modifications are consistent with the existing code style and structure of the file. The change is straightforward and I have no suggestions for improvement.
