- Add auth guard to Makefile start target
- Add license bullet and update start section in README
- Upgrade checkout@v3→v4, setup-node@v3→v4, Node 16→22, upload-artifact@v3→v4
- Replace deprecated LOCALSTACK_API_KEY with LOCALSTACK_AUTH_TOKEN

 ## Instructions
 
 You can build and deploy the sample application on LocalStack by running our `Makefile` commands. Run `make deploy` to create the infrastructure on LocalStack. Run `make stop` to delete the infrastructure by stopping LocalStack.
