/**
* Experimental new usePaginatedQuery implementation that will replace the current one
* in the future.
*
* Load data reactively from a paginated query to a create a growing list.
*
* This is an alternate implementation that relies on new client pagination logic.
*
* This can be used to power "infinite scroll" UIs.
*
* This hook must be used with public query references that match
* {@link PaginatedQueryReference}.
*
* `usePaginatedQuery` concatenates all the pages of results into a single list
* and manages the continuation cursors when requesting more items.
*
* Example usage:
* ```typescript
* const { results, status, isLoading, loadMore } = usePaginatedQuery(
* api.messages.list,
* { channel: "#general" },
* { initialNumItems: 5 }
* );
* ```
*
* If the query reference or arguments change, the pagination state will be reset
* to the first page. Similarly, if any of the pages result in an InvalidCursor
* error or an error associated with too much data, the pagination state will also
* reset to the first page.
*
* To learn more about pagination, see [Paginated Queries](https://docs.convex.dev/database/pagination).
*
* @param query - A FunctionReference to the public query function to run.
* @param args - The arguments object for the query function, excluding
* the `paginationOpts` property. That property is injected by this hook.
* @param options - An object specifying the `initialNumItems` to be loaded in
* the first page.
* @returns A {@link UsePaginatedQueryResult} that includes the currently loaded
* items, the status of the pagination, and a `loadMore` function.
*
