Previous Work

This commit introduces a significant improvement to the Streamlit app's user interface by merging the file upload and directory processing modes into a single, more intuitive workflow. Key changes include:

- Added a radio button to select between file upload and directory processing
- Unified the UI for both Excel and Word file types
- Maintained all existing functionality
- Simplified sidebar instructions
- Improved error handling and progress tracking
- Kept ZIP download feature for multiple file uploads

The new interface provides a more consistent and user-friendly experience while preserving the app's core functionality.
