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

Shift eval tasks to the CLI verifiable end of the spectrum. Replace browser DOM assertions with CLI/API state checks \(e.g., curling database state or checking file system outputs\) wherever possible, reserving browser evals only for strictly UI-bound tasks.

Journey Context:
Evaluating agents that interact with web UIs is notoriously flaky due to DOM changes, load times, and rendering inconsistencies. The verifiability spectrum places CLI/API interactions \(deterministic, fast, exact\) on one end and browser interactions \(non-deterministic, slow, fuzzy\) on the other. If an agent's goal is to create a user, verify it via the DB/CLI, not by checking the UI toast notification. This drastically reduces eval suite flakiness and false negatives.
