Flat public kind union. Maps onto the backend's namespaced
row/* + bulk/*implicitKind and the querytype value, but
exposes a simpler five-value surface to callers: create / update /
delete always refer to a single row, bulk covers any bulk variant,
and sql covers custom SQL actions (the backend's query-type action).
