refactor: streamline imports and improve null checks

This commit makes several refinements across the main.py file for better readability and performance:
- Simplified the import statements by removing unused imports, such as `ConfigParser` and `stream_with_context`, and consolidating uses of `urllib.parse`.
- Enhanced code clarity by replacing `!= None` checks with the more Pythonic `is not None` for better readability and to adhere to PEP 8 recommendations.
- Omitted redundant variable assignments in functions where the variables were declared but not meaningfully used, focusing the logic and reducing memory usage slightly.
- Corrected a logical error in an if condition by ensuring a proper membership test with `"embedType" not in "file"` making the code not only more readable but also preventing potential bugs.

Together, these changes make the codebase leaner, more maintainable, and compliant with best practices.
