Add support for the scenario where we create a singleton stack for shared infrastructure alongside application stacks. For example, a singleton stack that provisions an Elastic Container Registry, and a CODE and PROD application stack that pulls images from the registry. Previously, we had to create work-arounds with multiple `App`s. BREAKING CHANGE: `RiffRaffYamlFile` can no longer be directly instantiated Instead of directly instantiating `RiffRaffYamlFile`, please use `RiffRaffYamlFile.fromApp`: ```ts // Before const app = new App(); new RiffRaffYamlFile(app); // After const app = new App(); RiffRaffYamlFile.fromApp(app); ```

BREAKING CHANGE
RiffRaffYamlFilecan no longer be directly instantiated. Instead of directly instantiatingRiffRaffYamlFile, please useRiffRaffYamlFile.fromApp:This impacts these repositories.
How to test
See added unit tests. Also see guardian/mobile-n10n#1683 as a practical example of using
RiffRaffYaml.fromStackin a repository that deploys multiple Riff-Raff projects.How can we measure success?
Supporting more scenarios.
Have we considered potential risks?
Most repositories will not be impacted by the breaking change as they use
RiffRaffYamlFileviaGuRoot. Those that directly instantiate an instance ofRiffRaffYamlFilewould need to check if this change allows them to remove some custom logic.Checklist
