The --accept-nth option was not being respected when using --filter mode. This caused fzf to output entire lines instead of only the specified fields. Added buildItemTransformer() helper function to consistently apply field transformations across filter mode (both streaming and non-streaming) and select1/exit0 modes. Fixes #4615
