Declare the Knative v1.22.0 substrate CPU requests set live on railiance01

Browse source 
Strategic-merge patches and a kustomization over the checksum-pinned
upstream assets, a runbook with the rollout-deadlock and HPA lessons,
offline tests, and RAIL-KNATIVE-WP-0002 with the railiance-cluster
installer handoff as a wait task. Verified read-only against live.
