Feature request: Configure certain extensions to be enabled in chat mode

[bendavis78]

There are times when I'd just like to chat with the model w/o making changes to code, but still want it to have access to extensions. For example, I want it to read documentation from an internal knowledge base, or look at code and github. I can put it into "approve" mode, but it still attempts to suggest changes and that's not ideal. Also sometimes I would just like it to use such tools automatically.

Ideally we would want goose to only call tools that do not make changes to the filesystem or any other state. I don't believe there is a standard way to do this other than to have the LLM guess at which tools are safe to use in chat.

One easy solution to this would be to just make it configurable in config.yaml. Just have a boolean option for chat_mode that we can set to True. This gives the user control over which tools they want to be used in chat.

This sounds like an interesting idea. The one thing that I am trying to understand is how you would make goose do tool calls it does in other modes in chat-only mode.

If you have a good solution on what to make configurable in config.yaml already, I'd highly recommend opening a PR with a solve!
