CPU limits cause CFS throttling even when nodes have idle capacity. Move to a request-only CPU model: keep CPU requests for scheduling fairness but remove all CPU limits. Memory limits stay (incompressible). Changes across 108 files: - Kyverno LimitRange policy: remove cpu from default/max in all 6 tiers - Kyverno ResourceQuota policy: remove limits.cpu from all 5 tiers - Custom ResourceQuotas: remove limits.cpu from 8 namespace quotas - Custom LimitRanges: remove cpu from default/max (nextcloud, onlyoffice) - RBAC module: remove cpu_limits variable and quota reference - Freedify factory: remove cpu_limit variable and limits reference - 86 deployment files: remove cpu from all limits blocks - 6 Helm values files: remove cpu under limits sections
