bugf: deploymentf: deployment [railway]good first issue
Description
Users can provide the workspace option to the wasp deploy railway launch command. We don't use that information to more precisely return the list of Railway projects here.
This will be helpful for #2926 since we'll be able to be more precise in our checks if a Railway project exists or not in the selected workspace.
As of 2026-04-16, the Railway CLI doesn't provide a --workspace or similar flag for the railway list command, so there's not an easy way to do this.
