[frontier] Vision agents make systematic errors on color and position tasks that seem trivial to humans

Add explicit OCR/annotation overlays or structured state extraction instead of relying on raw screenshots for color-coded or grid-based reasoning.

Journey Context:
OpenAI's CUA achieved only a 5.36% success rate on Wordle, not because of poor logic but because it systematically misidentified tile colors as the grid filled. Errors were worst at the center of the grid and increased with each attempt, matching the model's 2x2 patch tokenization boundaries. This exposes a broader failure mode: vision models do not reliably perceive color, small relative position, or dense grid state from a raw screenshot. Agents that need color-coded or grid-based reasoning should extract structured state explicitly—via OCR overlays, DOM attributes, accessibility values, or a dedicated perception tool—and feed that structured representation to the planner rather than asking the planner to read the pixels.
