Crate car_browser 

Browser automation and perception pipeline for the Common Agent Runtime.

This crate provides:

• BrowserBackend trait: abstract interface for browser automation
• Perception pipeline: converts raw browser state (screenshots + a11y trees) into structured UiMap data
• Browser tool registration: registers browse_* tools with car-engine

Architecture

car-browser is backend-agnostic. Consumers provide a BrowserBackend implementation:

• Hydra provides TauriBackend (drives Tauri’s WebView)
• Headless uses ChromiumBackend (chromiumoxide, behind chromium feature)
• Tests use MockBackend
