[frontier] Agent context window overflows during long computer-use tasks despite text fitting within limits

Implement hierarchical visual summarization: maintain last 3 screenshots at native resolution, next 10 at 512px thumbnails, and older history as parsed semantic text descriptions retrieved via RAG

Journey Context:
Raw screenshot sequences consume tokens rapidly \(1080p ≈ 4000\+ tokens\). Naive approaches either drop history \(lose state\) or compress uniformly \(lose OCR fidelity\). The pyramidal approach preserves high-fidelity recent state while maintaining semantic coherence for ancient history via structured scene graphs rather than pixels.
