Disable tools until we handle them properly

Newer versions of continue use tools with Anthropic to perform
modifications. We or litellm (to be investigated) don't handle that well
which means that file modifications don't surface in chat.

Let's just pretend the client didn't ask for tools to be used until we
fix that.
