♻️ Reproduction Steps

1. Setup CopilotKit with local runtime
2. Configure onError in CopilotRuntime instance
3. Add some headers to the request
4. Simulate a situation when an error is thrown
5. onError doesn't provide request headers in errorEvent.context.request.headers

We need it to pass our own context data (mainly user ID) to the error handler, to be able to connect the error log to actions of particular user

✅ Expected Behavior

onError gets all possible data (or at least headers) it exposes in its contract from the request

❌ Actual Behavior

onError handler is missing request data, primarily headers
