Refactor extraction system and reorganize project structure

- Remove obsolete documentation files (DEPLOYMENT.md, PLAN_IMPLEMENTARE_S8_DETALIAT.md, README.md)
- Add comprehensive extraction pipeline with multiple format support (PDF, HTML, text)
- Implement Claude-based activity extraction with structured templates
- Update dependencies and Docker configuration
- Reorganize scripts directory with modular extraction components
- Move example documentation to appropriate location
