[First-time contributor] Looking for beginner-friendly issues to contribute

[1printf]

Hi maintainers! 👋

I'm a first-time contributor looking to get involved with this project. I have experience with Python, LangChain, RAG systems, and AI application development.

I'd love to contribute with:

• Bug fixes (especially beginner-friendly ones)
• Documentation improvements
• Test coverage additions
• Small feature enhancements

Could you point me to any good first issues or areas where newcomers can help? I'm happy to start small and work my way up.

Thanks!
