## Title

    Proposed fix: [llama-server] Agent history ending with assistant turn: "Cannot continue an assistant message that contains tool calls." / "Cannot have 2 or more assistant messages at the end of the li

## Body

    Recommended action: Ensure every assistant tool_calls message is followed by tool results before the next request and merge consecutive assistant messages; or start the server with --no-prefill-assistant (LLAMA_ARG_PREFILL_ASSISTANT) so a trailing assistant message is treated as complete.
    
    Option: Disable assistant prefill or fix history [evidence: official_recommended_action]
    Applies when: Agents replaying histories
    Steps:
    1. llama-server ... --no-prefill-assistant
    2. or append tool results after assistant tool_calls messages
    Expected: Requests accepted
