Terminal chat: Consider UX for buttons when there are multiple chat blocks

[Tyriar]

When there are multiple code blocks we still just have "Run" and "Insert", but it's not clear that it will work on the first block only. Should we special case it such that if there are multiple code blocks the buttons change to "Run First" and "Insert First"?

I wondered about this and thought we'd discussed forcing the LLM to give us only one code block, (or more strictly filtering its response) which would make this unnecessary.

With the coming chat location I was thinking we'd keep the terminal chat as is, but make @terminal inside the chat view more verbose. It already almost always gives a single block unless you really push it in which case it's kind of expected to have multiple code blocks. I don't think we'd be able to gracefully handle all cases where there's more than one block by removing some of them, there are also other agents that can give whatever they want, so it'll always be an edge case.
