feat: automatically pause active task when starting new task

[Pertempto]

It would be great if the app would automatically pause the running task when I start a new task. That way I don't have to pause the current task before starting a new one.

@LeanMendez would this match your workflow or do you use this in a way that you want multiple tasks active at once?

For my workflow, it's important that there is always only one task active at a time. Maybe that is not the case for you?
