Ship the Self-hosted Cloud release image #996

Parent

Spec: 1.0 tree cleanup and release contracts

What to build

Build and document the released Cloud image and compose deployment for web, worker, Inngest, Redis, and Postgres with operator-owned GitHub apps, following Self-host packaging for Cloud.

Acceptance criteria

• A fresh self-host install starts web and worker with the required environment and no Polar token.
• Image tags and migration/readiness behavior match the packaging decision; relay, Hosted DNS, installer, and binaries remain shared infrastructure.

Blocked by

• Make Cloud config and billing optional for self-hosters
• Squash Cloud schema to one fresh Postgres baseline
• Self-host packaging for Cloud #978
