typing exit within AI mode should be the same as hitting ESC

You: exit

I understand you want to exit. Thank you for using the CQL assistant. If you need help with Cassandra or CQL in the future, feel free to ask.                            

Sometimes it tells me it can't do that and can only run CQL queries.

Currently, the AI mode is not a command line invocation prompt. I'll think about what the best solution is here.
