[frontier] Screenshot agents fixate on visually salient elements while missing functional hidden controls

Combine accessibility tree structure with visual saliency maps; weight DOM semantic importance over pixel brightness when selecting interaction targets

Journey Context:
Raw pixel inputs cause agents to click colorful buttons while missing hamburger menus or keyboard shortcuts. Pure vision misses ARIA labels; pure DOM misses visual affordances. The solution uses accessibility trees as semantic masks over screenshots, grounding vision in function not just appearance. This prevents the 'colorful button bias' where agents ignore gray-scale functional elements.
