[research] Outcome-based evals pass while the agent uses suboptimal or dangerous tools

Implement trajectory-based evals. Score the agent not just on the final answer, but on the sequence of tool calls. Penalize paths that use destructive tools or take 5 steps for a 1-step task.

Journey Context:
An agent might successfully find a file by recursively searching the entire filesystem, but a production-ready agent should use grep efficiently. Outcome evals miss inefficiencies and security risks. Trajectory evals enforce that the agent reasons correctly, not just stumbles upon the answer.
