New UI shows when a tool's result arrives late, including how long the wait took

What

Claude Code has new on-screen messages for when a tool call's result comes back after the conversation has already moved on. If a result shows up late, you'll see a placeholder line noting that an earlier tool's result has arrived. If the assistant paused to handle a new message from you while a tool was still running, a line now reports how long that tool took to finish.

Why

This makes it clearer when results are arriving out of order, so you're not confused about why a tool's output appears after the conversation has already continued.
