Add a global setter function to allow injecting an external AsyncLocalStorage instance. This enables sharing a single AsyncLocalStorage across multiple request sources in applications that handle requests from various origins. Use cases: - Fastify HTTP requests - Queue consumers (e.g., RabbitMQ, SQS) - Scheduled tasks and timers - Other HTTP servers or frameworks - WebSocket connections Previously, the plugin sticked to its own AsyncLocalStorage instance, making it difficult to maintain a unified request context across different entry points. By providing setAsyncLocalStorage(), users can now create a central AsyncLocalStorage instance and share it across all request handlers, without coupling non-HTTP code to Fastify. Usage: ``` const sharedALS = new AsyncLocalStorage() setAsyncLocalStorage(sharedALS) app.register(fastifyRequestContext) ```
