[frontier] Context window overflow when processing video frame sequences for UI automation

Compute pixel-level diffs between consecutive frames and only feed bounding boxes of changed regions to the vision model; treat static backgrounds as cached context.

Journey Context:
Processing every video frame as a new image quickly fills 128k context windows. Static backgrounds \(wallpaper, browser chrome\) waste tokens on repeated information. By computing perceptual hashes or simple pixel diffs between frame N and N-1, agents can identify 'visual delta' regions. Only these bounding boxes are encoded as new image tokens, reducing a 60fps video stream to ~2-3 significant visual events per second while maintaining awareness of full context.
