…(/exp) to exclude metadata Add "nm=true" as a query parameter to exclude headers in CSV exports. This is useful for scripting data-based monitoring tasks. Example, return ingestion lag in milliseconds: ``` $ curl -G "http://localhost:9000/exp" --data-urlencode "query=SELECT (now () - max(timestamp)) / 1000 from trades;" --data-urlencode "nm=true" 210 ``` This returns only the query result, omitting any metadata, which allows monitoring without requiring additional post-processing. Additionally, the 'nm' parameter was already supported in the JSON (/exec) endpoint, and this PR enhances the consistency of the QuestDB REST interface. Fixes #4629
