Fixes #1095

Update useLiveQuery types to use InferResultType<TContext> which correctly
handles the SingleResult type marker, returning `T | undefined` for findOne()
queries instead of always returning `Array<T>`.

Changes:
- Import InferResultType, SingleResult, NonSingleResult from @tanstack/db
- Update UseLiveQueryReturn interface to use InferResultType<TContext>
- Add UseLiveQueryReturnWithSingleResultCollection for singleResult collections
- Add separate overloads for pre-created collections (NonSingleResult vs SingleResult)
- Update runtime implementation to return first element for singleResult collections

This aligns Vue adapter behavior with the React adapter.
