[feat] Allow the user to interrupt the AI with more context

[drfarrell]

Describe the feature

Allow the user to type into the search box and "insert" more into the conversation. This is helpful for guiding the AI away from doing something that it doesn't need to, or for adding in additional context for large changes.

Not sure what you mean by insert more into conversation. What's the search box?

[drfarrell]

@Kitenite I mean if the conversation is in-progress, allow the user to add a message into (i.e. "insert") the conversation without disrupting the initial flow.

Essentially enable the chat input to allow users to interject while chats are streaming.
