stream: fast-path stateless transform flush results
Avoid generator-based normalization for common flush result types in fused stateless stream/iter transforms. This keeps the corrected flush ordering while reducing overhead for already-normalized batches and primitive byte outputs.

stream: fast-path stateless transform flush results

fused stateless stream/iter transforms. This keeps the corrected flush
ordering while reducing overhead for already-normalized batches and
primitive byte outputs.
