feat(llmrec): 录制请求体补记实际发出的思考参数

Recorder 携带配置级 thinking_type/reasoning_effort（这些在 norma buildBody 里从
provider 配置注入 HTTP body，不在 CompletionRequest 上，故录制原先完全看不到）。
序列化时写入 thinking:{type,effort}，type 取有效值——每请求 req.Thinking 覆盖优先
于配置级（如 compaction 摘要强制 disabled），与 buildBody 判定一致。前端录制查看页
原样美化 JSON，自动展示该字段。
