[frontier] Pure screenshot agents miss hierarchical structure; pure DOM agents miss visual layout and dynamic states

Implement 'Selective DOM-Screenshot Fusion': use DOM for structural navigation \(finding elements, understanding hierarchy\) but capture targeted screenshots of specific elements for visual state verification \(checking if buttons are disabled, loading spinners active, or visual feedback present\).

Journey Context:
Screenshot-based agents \(Computer Use, browser-use with vision\) excel at understanding visual layout \('the submit button is below the form'\) but fail catastrophically on dynamic content—they cannot tell if a button is disabled, if text is selected, or if a dropdown is expanded unless explicitly visible in pixels. DOM-based agents \(Playwright, Selenium with LLM\) know the exact state of every element \(aria-disabled, selected options\) but lack spatial reasoning—they don't know that 'the blue button' refers to the visually prominent one, or that 'below the fold' means off-screen. The emerging pattern is hybrid: use DOM queries to locate elements structurally, then take targeted screenshots of just those elements to verify visual state, rather than full-screen shots or pure DOM inference.
