📚 Project restructuring and CI/CD setup

✨ Major reorganization:
- Move all documentation to docs/ directory
- Clean up root directory from temporary files
- Add comprehensive project documentation
- Implement Drone CI/CD pipeline

📁 Structure changes:
- docs/SCRIPTS_README.md - Complete scripts guide
- docs/DEPLOYMENT.md - Production deployment guide
- docs/API.md - Comprehensive API documentation
- patch/ - Temporary and test files
- Clean .gitignore with proper exclusions

🚀 CI/CD Pipeline (.drone.yml):
- Code quality checks (flake8, black, bandit)
- Unit and integration testing
- Docker image building and security scanning
- Staging deployment automation
- Production deployment on tags
- Telegram notifications
- Scheduled maintenance tasks

📖 Enhanced README.md:
- Technology stack badges with icons
- Drone CI build status badge
- Comprehensive quick start guide
- Clear project architecture
- Links to all documentation

🔧 Additional improvements:
- MIT License added
- .gitkeep files for important directories
- Improved .gitignore patterns
- Professional project presentation

🎯 Result: Clean, professional project structure ready for production
