Initialize the provider

The package exposes ObservabilityServiceProvider. The full routed facade registers it automatically; a slim application adds it explicitly:

import 'package:routed_core/routed_core.dart';
import 'package:routed_observability/routed_observability.dart';

Future<void> main() async {
  final engine = await Engine.create(
    providers: [
      ...Engine.defaultProviders,
      ObservabilityServiceProvider(
        ObservabilityConfig(
          metrics: ObservabilityMetricsConfig(enabled: true),
          health: ObservabilityHealthConfig(enabled: true),
        ),
      ),
    ],
  );

  // Health defaults to /readyz and /livez; metrics use /metrics when enabled.
  await engine.serve(port: 8080);
}

The provider supplies health, metrics, tracing, and error-observer services and connects their configured middleware. Configuration is validated before provider boot and remains fixed for the lifetime of the engine. The registry helper is retained only for discovering the default provider in the facade; custom configuration should be passed to ObservabilityServiceProvider.
