How to add Aspire to an existing ASP.NET Core solution without restructuring it

Add Aspire 13.4 to a brownfield ASP.NET Core solution by adding two new projects and three lines per service: aspire init, AppHost wiring with AddProject and WithReference, keeping your existing launchSettings.json and connection strings, and the resilience, health-endpoint, and proxy gotchas that bite on day one.
