Summary

Bump worker kubelet.extraConfig.maxPods from the default 110 to 150 via the Talos worker_config_patch local in the talos-cluster module. Unblocks HOMELAB-954 (WorkAdventure pods Pending due to FailedScheduling / Too many pods on wk-01; wk-02 cordoned pending HDD replacement).

Apply (Atlantis offline — manual)

cd prod/terraform
terraform plan -out=956.tfplan
terraform apply 956.tfplan

Expected plan shape: updates talos_machine_configuration_apply.worker["prod-wk-01"] and .worker["prod-wk-02"] in place. Talos reloads kubelet without a full node reboot.

Verify after apply

kubectl get node prod-wk-01 -o jsonpath='{.status.capacity.pods}{"\n"}'   # 150
kubectl get pods -n workadventure                                              # back-0 + redis-master-0 schedule
kubectl get app -n argocd workadventure                                        # Synced + Healthy

wk-01 is capped at the kubelet default (110 pods/node) and, with wk-02
cordoned pending HDD replacement, new deploys (observed on HOMELAB-954
WorkAdventure) hit FailedScheduling / "Too many pods". Raise the cap via
the worker config patch so there's headroom for the current stack
(harbor, temporal, longhorn, monitoring, etc.) plus new workloads.

Adds `kubelet.extraConfig.maxPods = 150` to the worker_config_patch
local. Applies to every worker via the existing
talos_machine_configuration_apply.worker loop. Talos reloads kubelet
in place — no full node reboot.

Apply path (Atlantis is offline, manual for now):
  cd prod/terraform && terraform plan -out=956.tfplan
  terraform apply 956.tfplan

Verify after apply:
  kubectl get node prod-wk-01 -o jsonpath='{.status.capacity.pods}{"\n"}'
  # expect: 150

Unblocks HOMELAB-954 (WorkAdventure pods currently Pending).
