 * Honeycomb telemetry adapter.

 * Configures the OpenTelemetry Node.js SDK with an OTLP exporter
 * pointed at Honeycomb. Once connected, all spans created by HotMesh
 * (workflow executions, activity calls, stream routing) are
 * automatically exported to Honeycomb.
 *
 * HotMesh uses `@opentelemetry/api` internally to create spans. This
 * adapter provides the TracerProvider + exporter that captures them.
 *
 * Usage:
 * ```typescript
 * import { telemetryRegistry } from './lib/telemetry';
 * import { HoneycombTelemetryAdapter } from './lib/telemetry/honeycomb';
 *
 * telemetryRegistry.register(new HoneycombTelemetryAdapter({
 *   apiKey: process.env.HONEYCOMB_API_KEY,
 *   serviceName: 'my-app',
 * }));
 * await telemetryRegistry.connect(); // before starting workers
 * ```
