[research] Agent evals for browser/UI interactions are flaky and unreliable due to non-deterministic rendering

Shift evals from visual DOM assertions to network-layer/API-layer verification. Intercept HTTP requests generated by the browser agent and assert against the payload, bypassing the UI entirely for regression suites.

Journey Context:
Browser automation is notoriously flaky for evals because load times, A/B tests, and dynamic classes change constantly. An agent might click the right button, but the DOM assertion fails due to a CSS change. By verifying the effect \(the API call fired\) rather than the action \(the DOM state\), you get CLI-level verifiability for browser-level tasks. Reserve visual assertions only for final end-to-end smoke tests, not regression.
