* fix(loop-detection): defer warn injection to wrap_model_call The warn branch in LoopDetectionMiddleware injected a HumanMessage into state from after_model. The tools node had not yet produced ToolMessage responses to the previous AIMessage(tool_calls=...), so the new HumanMessage landed *between* the assistant's tool_calls and their responses. OpenAI/Moonshot reject the next request with "tool_call_ids did not have response messages" because their validators require tool_calls to be followed immediately by tool messages. Detection now runs in after_model as before, but only enqueues the warning into a per-thread list. Injection happens in wrap_model_call, where every prior ToolMessage is already present in request.messages. The warning is appended at the end as HumanMessage(name="loop_warning") — pairing intact, AIMessage semantics untouched, no SystemMessage issues for Anthropic. Closes #2029, addresses #2255 #2293 #2304 #2511.
