• Simplified Palette class in colors.py for displaying color palettes, now leveraging Pydantic for validation.

Changed

• Default model in Chat class constructor now uses the GPT_3_5_TURBO enum.
• Migrated run_cell to run_python to avoid naming confusion and deprecated run_cell.
• Updated documentation and examples to reflect the new tools namespace and usage patterns.
• Removed __required__ from extract_model_from_function in registry.py to suppress Pydantic warnings.

Fixed
