[Feature]: GPU usage widget in Wave (similar to CPU sysinfo graph)

[Painkiller-GH]

Feature description

Hi Wave team,

First of all, thanks for the great work on Wave Terminal.

I’d like to request a new feature: a GPU usage widget, similar to the existing
sysinfo CPU widget.

Motivation

• Monitor GPU usage directly from Wave while working, without relying on
  external tools (Task Manager, MSI Afterburner, etc.).
• Keep CPU, RAM and GPU graphs together inside the terminal environment.
• Very useful for GPU‑bound workloads (ML, gaming, video processing, GPU‑accelerated
  applications, etc.) on any kind of GPU (NVIDIA, AMD, Intel, integrated or
  dedicated).

Desired behavior

• A widget that shows real‑time GPU utilization as a graph (percentage).
• Metrics that would be helpful:
  • GPU utilization (%)
  • VRAM / shared memory usage (MB / %)
  • Optionally temperature and power usage if available on the platform
• Behavior and look similar to the existing sysinfo CPU graph:
  • Configurable time window
  • Hover to see exact values
• If multiple GPUs are present, allow:
  • Selecting which GPU to display, or
  • Showing one graph per GPU.

Platform

• OS: Windows 11 Home (but the feature would be useful across platforms)
• GPUs: Any vendor/type (NVIDIA, AMD, Intel, integrated or dedicated)

Nice‑to‑have

• Simple configuration in the widget definition, e.g.:
  • type: "gpuinfo" or
  • Extend sysinfo to support metric: "gpu".

Thanks for considering this feature! I’d be happy to help test it.
