[frontier] Browser automation agents lose session state \(cookies, local storage, DOM scroll position\) when interrupted, forcing expensive re-navigation

Implement checkpointing that captures the full browser context via Chrome DevTools Protocol \(CDP\) - including session storage, cookies, exact DOM state, and viewport position; use this to 'hibernate' and 'thaw' browser sessions, allowing agents to resume exactly at the scrolled position and form state they left, even days later.

Journey Context:
Current computer-use agents restart browsers fresh each session. For multi-step tasks \(booking flights, complex forms\), losing state means starting over. The frontier pattern uses CDP to capture the complete browser VM state. This enables 'pause and resume' for cost-effective long-running web automation. Rather than keeping expensive browser instances open 24/7, agents hibernate to disk and resume on demand, maintaining exact user session continuity without re-authentication or re-navigation.
