[research] Agent evals are flaky because browser-based task verification is unreliable

Shift task verification to the CLI-verifiable end of the spectrum wherever possible. Use CLI tools \(e.g., git, pytest, curl\) for ground-truth evals instead of relying on DOM state or screenshot comparison.

Journey Context:
Browser environments have massive state spaces and non-deterministic rendering, making 'did the agent succeed?' hard to answer reliably. CLI tasks have deterministic exit codes and stdout/stderr, making them highly verifiable. If a task can be expressed as a CLI command or test suite, eval it that way. Reserve browser evals for strictly UI-bound tasks and accept higher variance.
