Llama 4 ipython Tool Output Synthesis in Multi-Turn

After returning tool outputs inside <|header_start|>ipython<|header_end|>...<|eot|>, append <|header_start|>assistant<|header_end|> so Llama 4 synthesizes the structured array into a clean natural-language answer.

<|header_start|>ipython<|header_end|> [ { "q3_revenue": "$14.2M" }, { "q4_revenue": "$18.9M" } ]<|eot|> <|header_start|>assistant<|header_end|>
