ci: migrate all workflows to GKE self-hosted runners

Swap all `runs-on: ubuntu-latest` to `runs-on: arc-runner-set` across
18 workflow files (35 job definitions). The ARM docker build job in
docker.yml uses `${{ matrix.runner }}` and is left untouched since
the GKE runner pool is x86_64 only.

Runners are backed by ARC (Actions Runner Controller) on a GKE cluster
with a spot preemptible node pool that scales 0→20 based on job demand.
Cost when idle: ~$25/mo (single e2-standard-2 for the controller).
