Report #91467

[frontier] Screenshot agents fail on dynamic loading states and non-deterministic UI timing

Implement explicit 'wait for visual stability' heuristics using pixel-diff thresholds between consecutive screenshots rather than relying on DOM readyState or networkidle events.

Journey Context:
DOM-based agents rely on document.readyState or networkidle0, but screenshot agents capture mid-animation frames or loading spinners because visual rendering decouples from DOM events. The common mistake is polling the DOM; the fix is visual diffing between consecutive screenshots to detect pixel-level stability \(e.g., <0.1% delta\), ensuring the UI has visually settled before action.
