[Copilot]

This PR implements a complete automation and user interface solution for the MD-Final-Prep repository, addressing all requirements in the issue:

🚀 New Features

1. GitHub Actions CI/CD Pipeline

• Automated testing on every push and pull request
• Dependency installation and environment setup
• Comprehensive test suite execution including:
  • Automation component tests (test_automation.py)
  • API functionality tests (test_md_exam_prep_api.py)
  • Text extraction tests (test_extract_text.py)
  • System configuration validation

2. Gradio Web Interface (app.py)

A user-friendly web interface that provides:

• System Status Dashboard - Monitor API server and data files
• Exam Predictions - Get AI-powered predictions for likely exam topics
• Topic Summaries - Quick medical topic overviews
• Content Search - Detailed medical content exploration
• Auto-starting API server - Seamless integration with existing FastAPI

3. Enhanced Dependencies (requirements.txt)

Updated with essential packages:

• gradio>=4.0.0 - Web interface framework
• pytest>=7.0.0 - Testing framework
• requests>=2.31.0 - API communication

4. Comprehensive Documentation Updates

The README now includes:

• Clear setup instructions for new users
• Web interface usage guide
• Testing guidelines with pytest integration
• CI/CD pipeline documentation
• Manual API testing examples

🖼️ Web Interface Preview

The web interface provides an intuitive way to interact with the medical study content through multiple tabs for different use cases.

✅ Testing & Validation

All existing functionality remains intact:

• ✅ Original automation scripts work unchanged
• ✅ FastAPI endpoints fully functional
• ✅ All existing tests pass
• ✅ New web interface integrates seamlessly
• ✅ GitHub Actions workflow validated

🎯 Quick Start

# Install dependencies
pip install -r requirements.txt

# Start web interface (includes API)
python3 app.py
# Access at: http://localhost:7860

# Or run automation only
python3 run_full_automation.py

The implementation provides exactly what was requested with minimal changes to the existing robust codebase, ensuring all current functionality continues to work while adding powerful new automation and interface capabilities.
