[research] Browser automation agent evals are flaky and unreliable compared to CLI agents

Map agent tasks to the verifiability spectrum. For browser tasks, do not eval DOM state directly; eval the underlying API/CLI equivalent or use accessibility-tree snapshots. Shift browser tasks to CLI/API equivalents where possible.

Journey Context:
CLI and API outputs are deterministic and easily verified by string matching or exit codes. Browser DOMs are notoriously mutable, dynamic, and non-deterministic \(e.g., class names change, elements shift\). Evaluating browser agents by checking exact HTML/DOM structure leads to 100% flaky evals. Instead, verify the outcome via a backend API or use accessibility-tree snapshots which are far more stable than raw HTML.
