/**
 * Infinite Query Factory - Generic wrapper for React Query paginated canister data
 *
 * Creates unified fetch/hook/invalidate functions for any paginated canister method.
 * Works with any Reactor instance.
 *
 * @example
 * const postsQuery = createInfiniteQuery(reactor, {
 *   functionName: "get_posts",
 *   initialPageParam: 0,
 *   getArgs: (cursor) => [{ cursor, limit: 10 }],
 *   getNextPageParam: (lastPage) => lastPage.nextCursor,
 * })
 *
 * // In component
 * const { data, fetchNextPage, hasNextPage } = postsQuery.useInfiniteQuery()
 *
 * // Flatten all pages
 * const allPosts = data?.pages.flatMap(page => page.posts)
 *
 * // Invalidate cache
 * postsQuery.invalidate()
