[research] Browser automation agents fail intermittently due to dynamic DOM rendering delays or popups

Inject explicit wait-for-state observability hooks in the browser context. Instead of relying on fixed \`sleep\` timers or immediate post-click evals, evaluate the DOM state via a polling trace span before proceeding.

Journey Context:
Browser environments are on the low end of the verifiability spectrum. An agent clicks a button, but the DOM takes 500ms to render the result. If the agent evaluates the page immediately, it sees stale data and fails or hallucinates. Fixed sleeps are brittle. The correct pattern is to emit a 'waiting for DOM state' span, evaluate the page using an accessibility tree, and only close the span \(and proceed\) when the target element is stable.
