/**
 * Logger Adapter
 *
 * Uses @plyaz/logger for observability output.
 * Can be used standalone OR alongside other adapters (Datadog, Grafana)
 * to always have console/file logging regardless of external providers.
 *
 * @example Standalone usage
 * ```typescript
 * const logger = new LoggerAdapter();
 * await logger.initialize({ serviceName: 'my-service' });
 * ```
 *
 * @example As console fallback with Datadog
 * ```typescript
 * const observability = new ObservabilityService({
 *   mode: 'parallel',
 *   adapters: [datadogAdapter, loggerAdapter], // Both receive all events
 * });
 * ```
 *
 * @module base/observability

 * Use this adapter:
 * - As standalone for development/debugging
 * - Alongside Datadog/Grafana to always have local console output
 * - As a fallback in priority mode when external providers fail
