+refactor(plugin-grid): `ObjectGrid`'s host-facing props types and its footer-summary reporter move into sibling modules
+
+Clause-②: no
+Metadata-protocol: none
+
+`ObjectGridColumnState`, `ObjectGridFooterSummary` and `ObjectGridExternalPaginationProps` move verbatim out of `ObjectGrid.tsx` into `objectGridProps.ts`, and the renderless `FooterSummaryReport` moves into `objectGridFooterSummaryReport.tsx`. No logic, name or rendered output changes. `ObjectGrid.tsx` re-exports the three types, so every name it exported before is still importable from the same path, and the package entry is unchanged.
+
+Correction to the slice 1 note: the record-source ladder (`getDataConfig`) stayed in `ObjectGrid.tsx`; it moved in neither slice.
+
+What to do: nothing.
