An empty positioned write beyond EOF currently grows an InMem file and zero-fills the gap. Confirm the intended compatibility behavior with the original fs author, then make zero-length writes no-ops and add focused sparse-write coverage if appropriate. Deferred from #1318 to avoid changing observable fs semantics in the refactor.
