Module config 

Built-in configuration support: appsettings.json + AppOptions pattern.

The framework automatically loads appsettings.json (merged with appsettings.Development.json in dev mode) and binds it to the built-in AppOptions struct. Users customize options via HostBuilder::configure(|app| app.useOptions(|o| { ... })).
