CI took about 5 min 10 s per PR on vm-201: 1.5 min of `pacman -Syu` and 3.5 min of build, half of it qmlcachegen compiling QML the tests never load. Now it takes **1 min 49 s with a cold ccache and 26 s with a warm one**. - CI runs in a prebuilt Arch image with the build deps (`git.trivk.dev/tri/qtpotato-ci:latest`). `ci-image.yml` rebuilds it weekly, when its Dockerfile changes, or on demand. It builds on the runner's own Docker daemon, so vm-201 has the new image right away, since the runner does not re-pull tags it already has. - CI configures with `QT_QML_NO_CACHEGEN=ON` and no debug info. Release and AUR builds keep both. - ccache, kept between runs with `actions/cache`. - Docs-only changes (`README.md`, `LICENSES/`) skip CI. Pushing the image to the registry needed two workarounds. Gitea's Actions token cannot push container images, so it uses the `PACKAGE_TOKEN` secret from #21. Cloudflare rejects request bodies over 100 MB and `docker push` sends each layer in one request, so `regctl` (pinned by sha256) pushes the layers in 50 MB chunks. Giving vm-201 more vCPUs is left out; it is an infra change. Refs #20 Proof: on this PR, CI run 328 (cold ccache) took 1 min 49 s and run 332 (warm, 41/44 hits) took 26 s, both 8/8 tests. Image run 333 pushed the image, and the registry digest matches the runner's local image. A local build with the CI flags takes 74 steps instead of 154.
