The pazof/yavsc-build-env:debian12-dotnet10-android36-v1 image only
ships .NET 10 SDK + Android SDK + JDK 17, no Node. actions/checkout@v6
requires Node, so the job failed with 'exec: node not found'.
Replace actions/checkout with a direct git clone over HTTPS (Forgejo
anonymous is enabled), and init submodules recursively.
Also drop the bogus docker://image:tag runs-on: matcher, use just 'docker'
to match the runner's declared label name.
