根因: glm-5.1 不理解 oneOf+const 复杂 schema，发送 tool_calls 时
arguments 为空 {}。同时缺少从对话上下文提取用户意图的回退机制。
修复:
1. researcher input_schema 从 oneOf+const 改为扁平化属性 — glm 正确传参
2. loop_runner 增加 empty-input 回退 — 从最近用户消息注入 _fallback_query
3. researcher infer_action 增加 _fallback_query 分支处理
4. 调试日志降级 INFO→DEBUG (openai tool_calls delta, researcher input)
