Add Streamlit application for real-time OpenCV exploration

- Introduced app.py to implement a web interface for exploring various OpenCV filters and transformations using webcam input.
- Updated .gitignore to include Python cache files.
- Removed run.py as it is no longer needed for launching the application.
