Introducing deploy cli

The deploy CLI, part of the langgraph-cli package, introduces a streamlined process for deploying and managing agents from the command line, with the initial command, langgraph deploy, enabling single-step deployment to LangSmith Deployment. This integration facilitates the incorporation of LangSmith Deployment into CI/CD workflows using platforms like GitHub Actions, GitLab CI, or Bitbucket Pipelines, by automating the creation of a Docker image and infrastructure setup, including Postgres and Redis services. Additional commands allow users to manage deployments, such as listing, viewing logs, and deleting deployments, while new templates for deep and simple agents can be generated with langgraph new. The latest version of langgraph-cli, featuring these new commands, is available for use, and users are encouraged to provide feedback to enhance the developer experience.
