v0.13.1

Fixes

• Fixed: on Coolify, a project made before 0.12.8 answered 502 (Caddy:
  lookup frontend on 127.0.0.11:53: server misbehaving) and content
  changes never cleared the frontend's page cache. Coolify and Dokploy
  attach services to a network of their own, and a service without a
  networks key then loses the default network, where the frontend
  and backend aliases live. dstack update now adds
  networks: [default] to proxy, worker-prod, umami, db and
  cache in compose.yaml when it is missing; commit it and deploy
  again. New projects list it on every production service.
