Install before a release exists

Install a service before its release exists. The installation sits in a Waiting for release state and starts deploying automatically the moment a release lands in its release channel.
While an install is waiting, Ryvn surfaces the next step inline on the installation. If the service has releases on other channels, a one-click Add release to channel action shows up pre-filled with the latest. If the service has no releases yet at all, the install picks up automatically as soon as the first one lands.
