name: Build wlroots (patched)

# The desktop's wlroots (Arch Linux ARM's wlroots0.20, what the desktop package's labwc links)
# rebuilt with tools/wlroots/patches: a Vulkan DMA-BUF allocator for the Adreno node, which is not
# a DRM device, so labwc's vulkan and gles2 renderers can start. Built in an Arch Linux ARM
# container on an arm64 runner and published as a release asset the apk build fetches
# (tools/wlroots/release.env names the tag and sha). The hosted desktop package is never changed.
