Maui Dependency Injection skill: what it does and how to install it

What it does. Guides .NET MAUI DI setup in MauiProgram.cs, covering service, ViewModel and Page registration, lifetime selection, constructor injection and Shell route resolution. It also covers platform-specific implementations, query parameters, testable interfaces and common scope and XAML timing pitfalls.

When to use it. Use it when wiring services or navigation-resolved pages in a .NET MAUI app. Do not use it for XAML data binding, Shell route configuration and query parameters, or mocking frameworks and test runners.
