Say that a deploy keeps only an app's volumes when the app has none (closes #248)

An app with no volume mounts now shows, in its Volume Mounts section, that the files it writes are lost whenever a deploy or rollback replaces its container and that a restart keeps them. Each deploy of such an app writes the same sentence into its log, after the webhook payload and before the clone. The README says in one sentence that a deploy or rollback starts a new container that keeps only the files in the app's volume mounts. Model: opus-5-5
