refactor: reorganize project structure for better maintainability
- Move Docker files to build/docker/ - Move CI/CD configs to build/ci/ - Move deployment configs to deploy/ (helm, k8s, argocd) - Move config files to config/ - Move scripts to tools/ - Consolidate assets to assets/ (Reflex compatible) - Add data/ directory for local data (gitignored) - Update all path references in Makefile, Dockerfile, CI configs - Add comprehensive README files for build/ and deploy/ - Update project documentation Benefits: - Clear separation of concerns - Cleaner root directory - Better developer experience - Enterprise-grade structure - Improved maintainability
