gsxdsm 1d6bb08e79 FN-7437: bound planner fallback retries

Bound planner fallback retries so model exhaustion reports a clear terminal error instead of looping.

- Add planner fallback exhaustion state and loop-limit handling for triage and pi planning paths.
- Report exhausted provider/model fallback attempts with actionable error details.
- Cover planner fallback exhaustion with engine regression tests and add a patch changeset.
