[frontier] Visual anchor drift in long-horizon agent tasks

Use 'Visual Anchor Hashing'—compute perceptual hashes \(pHash\) of critical UI regions at each step, compare against expected state before acting, fall back to DOM verification on mismatch

Journey Context:
Agents looking at full screenshots fail to notice when a checkbox becomes checked or a button becomes disabled after async operations. By maintaining perceptual hashes of interactive elements and validating state continuity, agents catch 'visual desync' where the UI changed but the agent's world model hasn't updated.
