[research] Agent evals flake wildly on browser/DOM tasks but pass reliably on CLI tasks

Separate eval suites by the verifiability spectrum. Use exact-match or deterministic assertions for CLI/API agents. For browser agents, use LLM-as-a-judge against a DOM snapshot or accessibility tree, and set a higher acceptable flake rate threshold.

Journey Context:
Browser environments are non-deterministic \(latency, dynamic ads, popups\). Treating browser evals like CLI evals \(checking specific pixels or exact text\) leads to infinite flake-chasing. The accessibility tree is more stable than raw HTML, but still requires probabilistic evaluation.
