refactor: functional separation with deploy/, recipe-generator/, and bin/

- deploy/: deployment bash scripts (4 files)
- recipe-generator/: recipe generation tool (Python + YAML configs)
- bin/: executable wrappers (single generate-recipe entry point)
- Updated deploy.sh, README.md, DEVELOPMENT.md, DEVELOPMENT_QUICK.md
- Updated tests/test_recipe_generator.py and tests/integration/test_integration.py
- Updated CI workflow and Makefile paths
- All 41 tests pass
