- Free ~14GB disk on GitHub runners (up from ~2GB) by removing additional unused pre-installed toolchains - Reduce KinD cluster from 3 to 2 nodes to lower disk and resource pressure - Add kubectl_apply_with_retry with exponential backoff for external URL fetches during cluster setup to survive transient 502 errors - Increase func deploy retries from 3/5s flat to 5/exponential backoff (10s-80s) to handle in-cluster-dialer pod instability

Parallel func deploy calls with the pack builder corrupt the shared ~/.pack/volume-keys.toml file, causing deterministic failures. Create a per-deploy temporary PACK_HOME directory when using the pack builder via the new EnvVars deploy option.
The pre-pull step is an optimization to avoid parallel pull contention during tests. If it fails due to transient network issues, the images will be pulled on-demand during the test run instead.
