Create a Prefect 3 work pool and deploy a flow for infrastructure-agnostic remote execution

Steps

1. Run 'prefect work-pool create my-pool --type process' (or kubernetes, ecs, cloud-run, etc.) to provision a work pool; work pools replace the Prefect 2 agent model and separate infrastructure configuration from flow code
2. Create a prefect.yaml file in your project root defining the deployment: flow entrypoint, work pool name, and build/push/pull steps for your container image if using a container-based pool type
3. Run 'prefect deploy' to register the deployment with Prefect Cloud and associate it with the work pool; Prefect reads prefect.yaml and creates or updates the deployment record
4. Start a worker process targeted at the pool with 'prefect worker start --pool my-pool'; the worker polls for submitted runs and launches infrastructure according to the pool's base job template
5. Trigger a run via CLI ('prefect deployment run my-flow/my-deployment') or via POST /api/deployments/{id}/create_flow_run; confirm the run is picked up by the worker within the poll interval (default 10 seconds)
