Jellyseerr stays and keeps talking to what it thinks is a Radarr, so the crate is a translation layer over the real domain and holds no state. Two of Radarr's ideas are absorbed rather than passed on: policy attaches to a root (DESIGN.md §5.1), so `qualityProfileId` on an add is read and dropped and `rootFolderPath` decides which policy a request lands under; and `searchForMovie` is dropped because the reconcile loop already searches whatever is wanted (§8).
