Idea

So we are going to send you a UIEvent which says Exceeding context window as a warning on the chat panel. We will get the UIEvent and then we have to pipe it all the way to the editor properly such that it works and shows up as a small red warning signal on the exchange (all the UIEvent's have the exchange_id supplied)
Make sure to follow the same abstractions we are using for the other framework events where it goes through the whole extension layer to the editor layer.

Use npm run compile at the end to verify your work (if the command does not work its fine leave it)
