Change ACTIONS_RUNNER_USE_KUBE_SCHEDULER to ACTIONS_RUNNER_DISABLE_KUBE_SCHEDULER
to make affinity-based scheduling the first-class (default) implementation.
Breaking Change:
- OLD: Set ACTIONS_RUNNER_USE_KUBE_SCHEDULER=true to enable affinity (opt-in)
- NEW: Affinity is enabled by default, set ACTIONS_RUNNER_DISABLE_KUBE_SCHEDULER=true to disable (opt-out)
Code changes:
- utils.ts: Rename constant and invert useKubeScheduler() logic
- rwo-affinity-test.ts: Update tests to verify default affinity behavior
- ADR 0135: Update to reflect opt-out model
- README: Update guidance to reflect default behavior
