[research] Agent evals are flaky because browser-based actions are inherently unverifiable

Shift agent architecture toward CLI-verifiable or API-verifiable tasks wherever possible. Use browser automation only when strictly necessary, and rely on accessibility tree assertions rather than visual pixel matching for evals.

Journey Context:
Browser environments have massive state spaces and non-deterministic rendering latencies. CLI commands return structured stdout and deterministic exit codes. Evaluating a browser agent requires waiting for DOM stability, which is fragile. Restructuring the task to use an API or CLI reduces the verifiability gap and makes regression suites reliable.
