Q LSP: expose actions as "code actions"

[justinmk3]

Problem

Q clients commonly provide features like Explain, Optimize, etc., which require very little UI (they send a canned query about code, and return chat responses). But even though the UI is simple, each Q LSP consumer must build this explicitly.

Proposal

Expose code actions for basic features such as Explain, Optimize, etc.

This needs more thought, but at least initially these actions could easily be provided:

• Explain: sends an "explain this code..." query and shows the response in a 'window/showMessage' event.
• Optimize: sends an "optimize this code..." query and shows the response in a 'window/showMessage' event.
• Use window/showMessageRequest to prompt user to select choices from a menu. ref
• ...others?

This gives an "instant UI" for any LSP client that supports LSP code actions, without any explicit integration with Q LSP.
