[frontier] Screenshot-only agents fail on canvas, WebGL, or dynamically rendered content

Implement hybrid vision: combine screenshot pixels with accessibility tree and semantic DOM structure for semantic grounding

Journey Context:
Pure pixel-based agents struggle with semantic understanding of UI elements, especially in canvas-based applications \(Figma, Google Maps, games\) where DOM structure is minimal or obfuscated. Conversely, pure DOM agents miss visual styling, layout information, and canvas content. The accessibility tree \(via Chrome DevTools Protocol CDP or OS-level MSAA/UIA APIs\) provides semantic structure \(roles, labels, states, bounding boxes\) that complements raw pixels. This hybrid approach allows agents to reason about both appearance \(screenshot\) and meaning \(accessibility tree\), enabling interaction with canvas elements by using the accessibility tree for semantic targets and screenshots for visual verification.
