[research] Treating browser-based agent actions with the same confidence as CLI-based actions

Map agent tasks to a 'verifiability spectrum' and apply different eval strategies: use exact match/exit codes for CLI/API tasks, but require multi-modal LLM-as-a-judge or DOM state snapshots for browser tasks. Never rely on string matching for browser evals.

Journey Context:
CLI tools return deterministic exit codes and stdout. Browser actions result in visual states that are non-deterministic \(latency, layout shifts\). Treating a browser action as 'successful' just because no exception was thrown leads to false positives. You must align the evaluation strictness with the determinism of the environment.
