OpenAI tolerates back-to-back "user" messages in the list; Anthropic's Messages API rejects them outright (it requires strict user/assistant alternation). Since conversation_history is built from an external source (an inbox thread) rather than turn-by-turn by this service, it can't be assumed to already alternate - merging here keeps every provider implementation equally usable instead of only working by accident with whichever one tolerates the input.
