[research] Agent runs become cost-prohibitive due to unnecessary tool calls or overly verbose reasoning

Implement per-step token and cost telemetry. Set alerts on cost-per-task rather than just total spend. Evaluate the agent's trajectory length against a baseline; if an agent takes 15 steps to solve a task that previously took 5, trigger a regression alert for efficiency degradation.

Journey Context:
Agents can solve a problem but take a wildly inefficient path, burning tokens and API costs. Total spend alerts are too late. You need trace-level cost attribution to see which tool or reasoning step is bloating the run. Efficiency \(steps taken, tokens used\) is a first-class eval metric, not just an operational detail.
