lab1 workers on both PVE nodes: per-node template + MD, balanced CA

Browse Source 
PVE is now the 2-node cluster homelab (pv1-1 + pv1-2), no shared storage:
- template 101 copied to pv1-2 as 9101; MDs lab1-workers-pv1-1 (max 6) and
  lab1-workers-pv1-2 (max 12), PMTs pinned with allowedNodes; pool .31-.50;
  lab1-workers renamed for symmetry (decision #18, #7 superseded)
- CA: balancing-label node.cluster.x-k8s.io/pool (+ pool label, capacity labels
  with os/arch, maxPods on the MDs), scan-interval 1m, v 2, default QPS (#19).
  Scale test: 16 pods -> 4 + 4 across both nodes.
- runbook, image-builder copy procedure, fixes tables, future task to report
  three CA clusterapi bugs upstream, lab facts, changelog, execution log

[2026-09-29-2315-pv1-2-workers](../plans/2026-09-29-2315-pv1-2-workers.md). It covers the bridge
fix, the template copy, the second MD, the CA limits and a decision row superseding #7.
- Update the "Lab facts" in CLAUDE.md/AGENTS.md: PVE cluster `homelab`, `pv1-2` at 192.168.0.10.
## Outcome (2026-09-30)
Done as planned, and confirmed on the lab:
- template 9101 on `pv1-2`;
- MDs `lab1-workers-pv1-1` (max 6) + `lab1-workers-pv1-2` (max 12);
- a balanced scale-up of 4 + 4 across both PVE nodes.
Two cluster-autoscaler findings from the scale test (no balancing, and throttling from uncached
discovery) led to decision #19. Details are in the
[execution log](../plans-executions/2026-09-29-2315-pv1-2-workers.md).
