gads-anomalieslisted

Routes to the `gads-anomalies` subagent. The agent runs: ``` python scripts/gads_anomalies.py --customer <id> --days 30 --baseline-days 14 --z 2.0 --json ``` When anomalies are found, the agent cross-references the change-event log via `gads-history` to see whether the spike correlates with a known account change.
