[frontier] Interaction Verification Loops: Vision models hallucinate interactive elements \('ghost buttons'\) that don't exist, causing agents to click empty space or wrong targets

Implement 'interaction verification loops': after attempting a click/scroll, immediately capture a new screenshot and verify that the expected state change occurred \(element disappeared, new element appeared, or visual diff detected\). If no change, rollback and replan.

Journey Context:
GPT-4o and Claude 3.5 Sonnet frequently hallucinate clickable regions on complex UIs \(dashboards, maps, canvas apps\), especially when elements look interactive but are disabled. The fix comes from reinforcement learning feedback loops in advanced agent systems. Common mistake: assuming VLM coordinates are ground truth. Alternative: using DOM element IDs, but many modern apps \(Figma, Google Maps\) don't expose stable DOM for canvas elements. Verification loops add latency but reduce error rate by ~60% in production systems.
