End-to-end deployment with Cline

Cline takes your requirements and builds the infrastructure. It uses `create_app` and `create_machine` to provision your entire stack from scratch. Once the machines are live, it uses `wait_machine` to confirm everything is running before it proceeds to the next step of your deployment script.

Real-time state monitoring

Cline keeps your app healthy by constantly checking statuses. It uses `list_machines` and `get_machine` to see if anything is drifting from your desired configuration. If it detects an issue, it can trigger `restart_machine` or `suspend_machine` to isolate the problem, keeping your downtime to a minimum.

Automated volume management

Cline manages your persistent storage by calling `list_volumes` and `get_volume` to track usage. If you run out of space, it doesn't wait for you to notice. It executes `extend_volume` automatically to prevent your database from locking up, ensuring your application stays available under heavy load.
