Add a simple example showing how to compose multiple middleware layers using `ServiceBuilder`. The example chains `ConcurrencyLimit`, `RateLimit`, and `Timeout` around a basic async service, demonstrating the core tower pattern of layered middleware. Tower currently has very few examples, and `ServiceBuilder` is the primary entry point for most users. This fills that gap.

Tower currently has only one example (
tower-balance), which is fairly advanced.ServiceBuilderis the primary entry point for most users, but there's no simple example showing how to use it. This fills that gap with a minimal, self-contained example.Checklist
