Report #64033

[frontier] Agents operating on video streams or rapid screenshots process redundant frames, burning context window and latency

Implement visual diffing or DOM mutation observers to only submit frames when state materially changes; use 'keyframe' approach similar to video encoding

Journey Context:
Streaming every screenshot at 1fps to an LLM quickly fills context windows with identical UI states. Production agents now use frame differencing \(pixel delta\) or, preferably, DOM mutation observers to detect actual changes. This reduces token usage by 10-100x and prevents the agent from 'overthinking' on static screens.
