Introduces `napi.CreateAyncWorker` for background tasks and `napi.CreatePromise` for handling asynchronous operations via deferred objects. Refactors the module export registration to use `go:linkname`, replacing the previous `entry.Register` function. Adds new examples demonstrating these features and the updated export style.
