Command Palette: Overlay Temperature Readings

### Description of the new feature / enhancement

I LOVE the new Command Pallet overlay that reads in CPU, Memory, Network, GPU it is perfectly placed and easy to read.
I would love to see the functionality expanded to include temperatures of CPU,GPU at a minimum with a stretch of pulling in other temps from say hard drives as well.

### Scenario when this would be used?

It's just nice to have a "single pane of glass" to be able to view live system metrics that may indicate an issue.

### Supporting information

_No response_

Start by locating the Command Palette overlay implementation and the existing CPU, memory, network, and GPU metric sources. Determine how temperature data could be sourced for CPU and GPU, with hard-drive temperatures as an optional extension. Done means the overlay shows live CPU and GPU temperatures reliably, with appropriate validation for supported hardware.
