Description

The overlay should be updated to support Vulkan.

On Windows and Linux, NVidia's Vulkan support is built on top of their existing GL driver. Thus, the current GL overlay might already work for NVidia cards.

For a native experience, the easiest thing to target for Vulkan would presumably be Intel integrated graphics on a Linux system. This should do for a POC.

Once we have a POC for Linux, this should be ported to Windows as well.

Research direction
Examine the existing GL overlay implementation (likely in src/overlay*) to understand how it hooks into graphics APIs. For Vulkan, investigate Vulkan's VK LAYER infrastructure or WSI extensions. Test initial proof of concept on Intel integrated graphics on Linux, then port to Windows. Review issue comments for any prior attempts or insights.
