Complete v2.0 transformation: Production-ready Flask application

Major Changes:
- Migrated from prototype to production architecture
- Implemented modular Flask app with models/services/web layers
- Added Docker containerization with docker-compose
- Switched to Pipenv for dependency management
- Built advanced parser extracting 63 real activities from INDEX_MASTER
- Implemented SQLite FTS5 full-text search
- Created minimalist, responsive web interface
- Added comprehensive documentation and deployment guides

Technical Improvements:
- Clean separation of concerns (models, services, web)
- Enhanced database schema with FTS5 indexing
- Dynamic filters populated from real data
- Production-ready configuration management
- Security best practices implementation
- Health monitoring and API endpoints

Removed Legacy Files:
- Old src/ directory structure
- Static requirements.txt (replaced by Pipfile)
- Test and debug files
- Temporary cache files

Current Status:
- 63 activities indexed across 8 categories
- Full-text search operational
- Docker deployment ready
- Production documentation complete
