 - `hermes-agent` is included only when `HERMES_AGENT_API_KEY` is configured. Set it to Hermes `API_SERVER_KEY`, or any non-empty value if that local server does not require auth. `HERMES_AGENT_API_BASE_URL` defaults to `http://127.0.0.1:8642/v1`; set `HERMES_AGENT_MODEL` only when you need an additional fallback/override model id.
 - The backend loads provider model lists at startup and refreshes them about once every 24 hours. If a later provider refresh fails, the response keeps the last loaded model list for that provider and sets `error` to the latest failure message.

-Behavior notes:
- `reuseByQuery` defaults to `false`, preserving the normal create-a-new-search behavior.
- When `reuseByQuery` is `true` and `query` is present, the backend normalizes the query with `trim().toLowerCase()` and returns the most recently updated existing search with that normalized query instead of creating a duplicate.
- `cacheHit` is `true` only when the reused search has persisted results or answer text, is not currently streaming, and was updated within the 24-hour search cache window. Clients can then fetch `GET /v1/searches/:searchId` and display it without running another search.
- If a matching search exists but `cacheHit` is `false`, clients may run the search again on the returned `search.id`; the run endpoints replace that search's persisted results and answer with the latest run.
