The flutter-ci runner image (CI-Runner/CI-flutter/Dockerfile) bakes in
Flutter 3.41.8 + Android cmdline-tools + platform-34 + build-tools
34.0.0 + JDK 17, so the workflow no longer needs subosito/flutter-action
to install everything per-job. Drops the setup step and switches
runs-on from the general-purpose go-ci to flutter-ci.
Per project memory feedback_dedicated_runner_labels.md: prefer
purpose-built labels with toolchains pre-installed over generic-runner +
setup-action ceremony on this self-hosted Forgejo deployment.
