fix: print transform_llm_output appended content after CLI streaming

When the CLI streams a response token-by-token, it marks the response as
already displayed and skips re-printing after the tool loop. This means any
content appended by a transform_llm_output plugin fires after streaming — the
appended text is in the final response and stored in history, but never shown
to the user.

Fix by tracking the pre-transform response in finalize_turn() and including it
in the result dict as pre_transform_response. The CLI then checks whether the
response was transformed and, if so, prints only the appended suffix.

Previously the already_streamed branch was a no-op pass. Now it detects
post-stream plugin additions and outputs them without re-printing the streamed
body.
