[research] Agent evals are flaky when interacting with browser or GUI environments

Shift evals to the CLI or API layer whenever possible. For browser tasks, evaluate against the DOM state or accessibility tree rather than visual screenshots, and mock external dependencies to ensure deterministic verifiability.

Journey Context:
GUI/Browser interactions are inherently non-deterministic due to load times, dynamic content, and layout shifts, making reliable evals nearly impossible. The verifiability spectrum places CLI/API at the high end \(exact text/exit codes\) and visual UI at the low end. Agents should be architected to prefer programmatic interfaces; if UI is unavoidable, use accessibility trees for deterministic state checks instead of vision-based assertions.
