The HostApi gains set_reference_only(handle, reference_only): a plugin can designate display geometry it owns and refreshes. The entity renders like any other, but the built-in edit paths treat it like an entity on a locked layer, while the owning plugin keeps full write access (update, erase, XDATA). - Appended at the trait tail with a refusing default so plugins keep compiling against older hosts; the loader gate range is untouched. - IPC: SetReferenceOnly / SetReferenceOnlyResult round-trip through the shared dispatch, the V3 client and the V4 client, with the shared document cache invalidated on success. - build.rs version_info and manifest API_VERSION bumped to 9 in lockstep. - Evidence: reference_only_request_and_response_roundtrip (bincode round-trip of the request and both response payloads).
