The job image (tools/ci/Dockerfile, label game-maker-ci) carries chromium with the Vulkan
drivers, php-cli and the host's fonts; the render device itself comes from the runner's
container.options, so a job container gets the Intel GPU instead of llvmpipe.
tools/ci/serve.sh puts the checkout behind /game-maker/ with php -S and writes the project
shells the seeders need; every tool now takes its server from GAME_MAKER_BASE_URL rather than
from a project id repeated in shell scripts.
