Subject: [PATCH 1/2] fix(react-db): make getNextPageParam optional in
 useLiveInfiniteQuery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

getNextPageParam is required in UseLiveInfiniteQueryConfig but is never
called — pagination is determined entirely by the peek-ahead strategy.

Mark it as optional with a @deprecated JSDoc tag so consumers aren't
forced to write dead code.

Fixes TanStack/db#1241
