Maintain focus

### Describe the feature or problem you'd like to solve

Copilot CLI has ADHD. Needs to focus

### Proposed solution

Copilot CLI has ADHD. When it's working on a task, and you ask it a question or want to append a new task, more often than not it will stop what it was working on, answer you, and do nothing more.

Contrast this with Claude Code, which you can have working on a complex issue or set of issues, managing a team of agents, monitoring background tasks, and you can still add something to it's agenda or ask a question. It will divert itself to address your issue, add item to the task backlog, or just record something for memory to answer later, and continue with what it was working on.

The Claude Code approach is a much better solution, and much better experience. This behavior alone is what prompted me to recommend to my org that the team adopt Claude Code as our primary coding agent, as otherwise Copilot CLI felt somewhat close enough, but that "stop, answer, do nothing more" behavior is so jarring as to make the cli feel almost useless for someone wanting to multitask.
