fix(metric_helper): correct trajectory save path and add tool call metric

- Change trajectory save directory from "ctx_trackers" to "trajectory" to organize files better
- Add recording of tool call counts alongside error rates in tool metrics
- Update experiment suffix in deep finance example script for clearer naming convention
