debug: Switch to ultra-minimal Streamlit test to isolate restart loop issue

- Create minimal_test.py with only basic Streamlit components
- Change app_file to minimal_test.py in README.md for HF Spaces
- Remove st.set_page_config() from main app temporarily
- Test if complex Streamlit components are causing restart loops
- Will identify root cause before re-adding functionality
