Auto-finalize ResponseStream on iteration completion (#4478)

* Add multi-turn streaming sample and rename multi-turn samples

- Rename 03_multi_turn.py to 03a_multi_turn.py
- Add 03b_multi_turn_streaming.py showing streaming with session history
- The new sample demonstrates calling get_final_response() after
  iterating the stream to persist conversation history
- Update READMEs to reflect the new file names

Closes #4447

* Auto-finalize ResponseStream on iteration completion

When a ResponseStream is fully consumed via async iteration,
automatically trigger finalization (finalizer + result hooks).
This ensures session history is persisted in streaming multi-turn
conversations without requiring an explicit get_final_response() call.

- Add auto-finalize call in __anext__ on StopAsyncIteration
- Guard inner stream finalization to prevent double-execution
- Re-check _finalized after iteration in get_final_response()
- Add tests for auto-finalization and streaming session history
- Revert sample file renames from previous commit

Closes #4447
