[synthesis] Extracting text from UI screenshots fails differently per model

For GPT-4o, crop the image to the relevant region before sending. For Claude, ensure text is legible at standard resolution and avoid extreme aspect ratios. For Gemini, add explicit instructions like 'focus on the text in the top right corner'.

Journey Context:
When building computer-use or UI-parsing agents, passing full screenshots is common. GPT-4o's vision pipeline aggressively downsamples and crops, missing small UI text. Claude's vision is more holistic but loses fidelity on tiny fonts. Gemini preserves detail but lacks implicit attention to non-central elements. The synthesis is that image preprocessing \(cropping\) is mandatory for GPT-4o, resolution enhancement is needed for Claude, and explicit spatial attention prompting is required for Gemini.
