B16: Test Timeout and Error Handling

[marc-romu]

What changed

SmartHopper 2.0.0 adds a configurable timeout and improves error handling across all AI components. Users can now set per-request timeouts and cancellation behavior through the AI Settings component.

How to test

---

Tests

• Default timeout: Place an AI component and run a prompt without any custom timeout. Verify the request completes normally within a reasonable time.

• Custom timeout - short: Place an "AI Settings" component. Set Timeout to 1 second. Wire to an AI component. Submit a complex prompt. Verify the request times out quickly with a clear timeout error message.

• Custom timeout - long: Set Timeout to 300 seconds. Submit a prompt. Verify the request is allowed enough time and completes successfully.

• Cancellation: Start an AI request, then set the Run input to false mid-request. Verify the request is cancelled gracefully - no crash, no hanging.

• Network error handling: Disconnect from the internet (or use an invalid API key). Submit a prompt. Verify the component shows a clear error message about the network/auth issue (not an unhandled exception).

• Rate limit handling: If possible, trigger a rate limit by sending many rapid requests. Verify the component reports the rate limit error clearly.
