[cost\_intel] Vision 'auto' detail bills high-detail tokens for images that only need low detail

Set detail explicitly to 'low' for presence/absence, layout, and icon questions; use 'high' only for small text or dense diagrams, and resize images to the low-detail budget when possible.

Journey Context:
GPT-4o charges ~85 tokens for low-detail images and ~765 tokens for a 1024x1024 high-detail image. The 'auto' setting picks high detail for images above 512px, so a routine screenshot can cost 9x more than expected. For most agent screenshots, low detail is sufficient unless the task is OCR. The quality signature is OCR accuracy and fine-grained spatial reasoning; if low detail gives the right answer, high detail is pure waste. Pre-size images to the model's low-res budget to avoid surprise scaling.
