[BUG] Slash commands are ignored while tasks/todos are in progress

What's Wrong?

Slash commands are ignored while tasks are in progress. The application continues through working on the todo list until it needs to ask permission or the todo queue is completed. In the case of the /compact command, tasks are adding context while the context limit is being reached and then exceeded, and by the time the command is run, it fails because of the context length limit.

What Should Happen?

Slash commands should take priority over current tasks or at least over future tasks
