AIThinking
A reply's thinking before any of it arrives: "Thinking…", counting the seconds.
AIConversation shows it under the latest question while the agent is thinking, counting from when the question was asked, and the reply's first reasoning step takes its place as "Thought for 8s". Anywhere else it counts from when it appears. It looks like the header of StreamingReasoning while the model thinks.
