[frontier] Context window exhaustion when interleaving screenshots with text reasoning in long-horizon tasks

Implement hierarchical visual summarization: convert screenshot histories into VLM-generated scene graphs, retaining only keyframes for pixel-perfect operations

Journey Context:
Screenshot tokens consume 1000\+ tokens each; agents hit context limits after 3-4 screenshots. Truncation destroys task history. Scene graphs \(object relationships\) compress visual state into structured text \(100 tokens\), while keeping only the latest screenshot for OCR/click coordinates. This balances semantic memory with pixel precision, unlike naive frame sampling which loses temporal continuity.
