When `enable_thinking` is false (e.g. via `chat_template_kwargs: {thinking: false}`),
the Kimi-K2 parser was still extracting reasoning tokens and routing all output to
`reasoning_content` instead of `content`.
The fix aligns with how other thinking models (Qwen3, etc.) handle this: check both
`reasoning_format != NONE` and `enable_thinking` before enabling reasoning extraction.
Fixes#1685
