[cost\_intel] Vision API cost explosion with high-resolution image processing

Force 'low\_res' mode for GPT-4o Vision unless OCRing fine text; 'high' res tiles 512px squares costing $85/1M tiles vs $0.005/image for low. A 2048x2048 image costs $0.0077 high vs $0.005 low.

Journey Context:
By default, GPT-4o Vision uses 'auto' which selects 'high' for images >512px on any edge. This tiles the image into 512px squares \($85 per 1M tiles\). A standard 1920x1080 screenshot becomes 8 tiles \($0.00068\), while low-res \(single 512px compression\) costs $0.000005. For image-heavy applications \(fashion cataloging, medical imaging\), defaulting to high-res multiplies costs by 100x. Only use high-res when the task requires reading small text \(<12pt\) or fine details. Implement client-side downscaling to 512px before API call to force low-res pricing.
