[frontier] Agent hallucinates UI elements when describing screenshots \(invents buttons that don't exist\)

Require pixel coordinates or bounding box verification for all visual claims

Journey Context:
Vision-language models hallucinate visual details—claiming buttons exist that don't, misreading text colors. Fix: Enforce 'visual grounding'—require the agent to output \[x, y\] coordinates or bounding boxes for any claimed element. If it cannot provide coordinates, it must admit ignorance. This dramatically reduces hallucination rates in computer-use agents.
