[synthesis] Agent retrieves unnecessary files padding the context window before failing

Track the ratio of retrieved context bytes to actually utilized bytes in the final generation. Alert when the retrieval-to-utilization ratio exceeds the historical baseline for a given task category.

Journey Context:
It is assumed that if an agent completes a task, the retrieval was successful. However, as embedding models drift or context management degrades, agents start pulling in just-in-case context. This padding does not cause immediate failure, but it pushes the context window closer to the limit, degrading the agent's reasoning on subsequent steps. Monitoring retrieval yield, not just retrieval success, catches this.
