+Remove the deprecated `useQuery` legacy query-field aliases — use the canonical Spec names (11.0).
+
+`UseQueryOptions` / `useQuery` / `useInfiniteQuery` no longer accept the legacy
+aliases `select` / `filters` / `sort` / `top` / `skip`. Use the canonical
+protocol names instead:
+
+| removed | use |
+|---|---|
+| `select`  | `fields`  |
+| `filters` | `where`   |
+| `sort`    | `orderBy` |
+| `top`     | `limit`   |
+| `skip`    | `offset`  |
+
+Behavior is unchanged for callers already on the canonical names.
