Optional Callback URL / Secret on the Start node (or x-callback-url header). Webhook now returns 202 immediately and POSTs SUCCESS, STOPPED (HITL), or ERROR to the callback URL, signed with HMAC-SHA256 when a secret is set. Retries 3x with 0s/3s/6s backoff.

Code Review
This pull request introduces asynchronous callback support for agentflow webhooks. It adds configuration fields for a callback URL and secret to the Start node, allowing the server to return a 202 Accepted response immediately while processing the flow in the background. Results are then dispatched to the specified URL with retry logic and optional HMAC-SHA256 signing. Feedback focuses on improving error message extraction in the background task by using a utility function instead of direct property access.
