"Accept" workflow for AI Code Edits #1165
Description
The user should be able to click an "Accept" button, alongside the existing "Undo" and "Try Harder" buttons, after receiving an AI result.
It should not be possible to type into the text area until the user clicks "Accept" (assume there's a parameter enableAIChatTextEntry we can pass into VZCodeContext - we will implement that in the other project later).
After clicking "Accept", the chat history should be cleared, and the user should be able to enter text again.
