Short alias
dotnet run — wolverine-diagnostics codegen-preview -g Greeter
The output includes the full generated class — the `Handle` or `HandleAsync` override, all
middleware calls in order, dependency resolution from the IoC container, and any
transaction-wrapping frames. This is identical to what `codegen preview` outputs, but scoped to
exactly one handler so the signal-to-noise ratio is much higher.
