      - Deploys the latest image to app workloads
      - Runs a release script before deploying if `release_script` is specified in the `.controlplane/controlplane.yml` file and `--run-release-phase` is provided
      - The release script is run in the context of `cpflow run` with the latest image
      - If the release script exits with a non-zero code, the command will stop executing and also exit with a non-zero code
