[research] Unreliable evals for browser automation agents compared to CLI agents

Shift browser agent evals to verifiable DOM states or CLI-accessible API endpoints rather than visual assertions. For CLI agents, assert exact stdout/stderr and exit codes.

Journey Context:
CLI outputs are deterministic and easily diffable \(exit codes, stdout\). Browser outputs are notoriously flaky due to rendering timing, dynamic DOM, and layout shifts. Agents evaluating browser tasks should check DOM accessibility trees or underlying network requests \(via HAR files\) rather than pixel comparisons or generic LLM-judged screenshots, moving the task up the verifiability spectrum.
