Describe the bug

Very often, when I open Task Manager to find out why my computer is running slow or the fans are running loud, and I find Warp at the top of the list for CPU usage... even though it's not doing anything! It's just sitting there in the background, no tasks are running.

To reproduce

1. Open a Warp terminal
2. Do some stuff in it
3. Close any running commands
4. (Optional) Switch to another virtual Desktop (that is, with Win+Tab)
5. Do something else on your computer for a while, or leave it idle

Expected behavior

Warp should use very few CPU/GPU resources while not actively running commands or agents, let alone if it's not even visible.
