[Feature request] Add copilot chat as a command and append the results to a buffer

[dc740]

Is your feature request related to a problem? Please describe.
I'm still configuring this, but I saw no reference to being able to use Copilot Chat.

Describe the solution you'd like
I'd like to run a command in Helix (even if it's an SH command) to ask a question in a copilot chat session, and see the response in a buffer dedicated to this conversation (so I can move it around Helix, split windows, etc).
This buffer would contain the question I entered as a command, and the response, and then each new question+response would still be in the buffer separated by some character and new lines.

Describe alternatives you've considered
Having a dedicated interactive window does not seem to be supported in helix? It'd be nicer
Getting the chat to suggest code would be OK, but having it in a buffer is more than enough.
