[frontier] Visual context drift in long-horizon GUI agents

Implement 'Visual Diff Anchoring' by maintaining a running binary diff mask between consecutive screenshots and injecting a text description of changed regions into the prompt every 3 steps to prevent attention drift.

Journey Context:
Teams often try to fix drift by increasing context window or resolution, but the real issue is attention dilution over long sequences. The diff mask acts as a 'visual memory anchor' without consuming excessive tokens. Tradeoff: extra compute for image diffing vs. accuracy. This is superior to frame stacking which explodes token count linearly.
