2. When clicking "run" from the middle panel, I notice that the AI chat panel gets wiped clear. (I also notice that the input panel flashes unexpectedly and then comes back.) Can you look into this?

@stuartc I think the chat gets cleared because the update callback of the LiveComponent gets called after the LiveView handle_params and that creates a new session.

I think we really need an external place to cache the session history to shield the user from losing the history maybe due to a liveview crash or something we don't account for.

@midigofrank @taylordowns2000 I've fixed the wiping of the chat state on clicking run here: https://github.com/OpenFn/lightning/pull/2216/commits/8363a28bf9f17585d58ea37edf4a2bc702ad65f6
