[frontier] Cross-modal grounding drift where referring expressions lose track across text and vision turns

Implement 'Visual Anchors' with UUID registry—assign persistent UUIDs to detected UI elements during vision turns, reference these UUIDs in text reasoning rather than descriptive phrases, and maintain an anchor registry mapping UUIDs to current DOM selectors and coordinates.

Journey Context:
When an agent sees a button in turn 1, refers to it as 'the blue submit button' in turn 2 \(text\), then tries to click it in turn 3, the description may match multiple elements, or the button may have changed state \(now gray, or text changed\). This is 'grounding drift.' Descriptive references are brittle across turns. The solution is 'Visual Anchors'—during the vision turn, detect all interactive elements \(using OmniParser, FAST, or similar\), assign each a UUID \(e.g., uuid-7f3a...\), record their bounding boxes and DOM selectors. In text reasoning, the agent thinks 'click uuid-7f3a...' not 'click the button.' The execution layer maps the UUID back to current coordinates. This persists across turns even if visual appearance changes \(as long as DOM structure is stable\), and prevents drift when the same description applies to multiple elements.
