/**
 * Provider-agnostic run-configuration types shared by backend and frontend.
 *
 * Lives in `shared/types/` so the OR adapter, the chat metadata layer, the
 * cron-scheduler dispatch path, and the UI pickers all reference the same
 * unions. Prior to this file these types were redeclared in
 * `backend/.../optionsAdapter.ts` and `frontend/.../localStorage.ts`; keeping
 * one definition prevents drift when OR adds a new effort level.
