[frontier] Coordinate-based actions accumulate pixel drift over scrolling/page changes, causing clicks to miss targets by growing margins

Use visual anchor refreshing: every 3rd action, re-ground all future target coordinates against current viewport using fresh screenshot and Set-of-Marks prompting, resetting the drift error accumulator to zero

Journey Context:
Absolute coordinates fail on responsive layouts, scrolls, zooms. Relative coordinates drift. Agents using 'click at x,y' without recalibration develop systematic error \(like dead reckoning in robotics\). The pattern is periodic re-grounding \(similar to SLAM loop closure\) every N steps or after scroll actions, preventing error accumulation that otherwise causes agents to miss small buttons after 10\+ steps.
