The Kubernetes backend copies actions and workspaces into job containers with `tar` over `pods/exec`, so every byte goes through the API server. On managed clusters that often sits in other zones than the nodes, so each byte can cross zones twice, and the copies load the API server. With `kubernetes.transfer.mode: auto` or `direct`, an init container copies `gitea-runner` into the job pod, and the job container fetches directories and copies of 64 KiB or more gzipped from the runner over the pod network. `auto` falls back to the API server for a job pod that cannot reach the runner, `direct` fails the job. Copies can hold secrets, so each is served once, over TLS 1.3 pinned to a certificate the runner generates, only to the job pod's IPs. Copying setup-go@v5, cache@v4, setup-java@v4 and build-push-action@v6 sends 11.6 MB through the API server on main and 532 B with this PR.
