The UI window is black on Linux with an NVIDIA GPU under PRIME offload: score runs on XWayland with QT_XCB_GL_INTEGRATION=xcb_egl, and Qt Quick's OpenGL window never shows there. Vulkan renders correctly on both the NVIDIA and Intel GPUs.

Adds environment.linux, which create-app.sh appends on Linux only, the same way Domeport does. macOS and Windows keep their defaults.

score runs on XWayland with QT_XCB_GL_INTEGRATION=xcb_egl, and with NVIDIA
PRIME offload Qt Quick's OpenGL window stays black there. Koaia, LivePose and
Domeport already pin Vulkan on Linux.
