Triple-C

Reported on CachyOS/Arch with Wayland: the app aborts immediately with
"Could not create default EGL display: EGL_BAD_PARAMETER. Aborting."
printed straight to stderr by WebKitGTK's own C code, before Triple-C's
own logging even gets a chance to say anything useful about it.

This is WebKitGTK's DMA-BUF renderer (its default accelerated-compositing
path since 2.42) failing on some Mesa/driver/compositor combinations. Set
WEBKIT_DISABLE_DMABUF_RENDERER=1 unconditionally on Linux before the Tauri
builder runs, which is where GTK/WebKitGTK actually read it — there's no
reliable way to detect the affected combination ahead of time (reports of
this exact failure exist under XWayland too, not just pure Wayland
sessions), and WebKitGTK's fallback compositing path costs some rendering
performance this app's UI doesn't need. Left alone if a user has already
set the variable themselves.

Does not address the other two things filed under the same issue (links
not opening on the host, and a request for a native Arch/CachyOS package)
— those need more information / are a separate scope, respectively.
