The weekly rolling OS-update cycle has been silently stripping docker.io from
worker nodes (DEV-498), breaking the Forgejo runner whose hostPath mount for
/var/run/docker.sock requires the socket to exist. Fix in two layers:
- Defensive pin: update-node.sh now runs `apt-mark manual docker.io` in the
apt phase (whenever it is installed) so `apt-get autoremove --purge` cannot
silently drop it during subsequent upgrades.
- Post-reboot reconciliation: new `ensure-node-docker.sh` installs docker.io
if missing, enables + starts the systemd unit, waits for /var/run/docker.sock,
and re-applies the `basicstack.de/docker=true` label. Wired into
update-node.sh between kubelet-Ready and uncordon. No-op on nodes without
the label (safe for cp-1 and the update runner).
Verified idempotent against all 5 labeled workers; `apt-mark manual docker.io`
now set on every worker (survived across reboots by design).

cp-1 is excluded from os-update.sh because a one-shot drain would trigger
the kine cascade documented in DEV-495. This adds:
- CP1_UPDATE_PROCEDURE.md: swap-add (Phase A), preflight, batched stateful
eviction (Phase C), drain+apt (Phase D), reboot with external livez
monitor (Phase E), uncordon+verify (Phase F), and rollback paths.
- scripts/os-update/update-cp-1.sh: subcommand-per-phase runner with the
same /tmp/os-update-cp-1-<ts>.log contract as update-node.sh; supports
--dry-run, --add-swap, --preflight, --drain-stateful, --apt, --reboot,
--finalize, --run.
- os-update.sh: explicitly excludes k3s-cp-1 with a pointer to the cp-1
script; kine thundering-herd guardrails preserved.
- OS_UPDATE_PROCEDURE.md: cross-reference to the cp-1 procedure.
Execution requires separate board approval; this change is design +
dry-run artifact only.

- infrastructure/OS_UPDATE_PROCEDURE.md: agent-facing rolling update
procedure (drain -> apt -> reboot -> verify -> uncordon -> health ->
next). Explicit MUST NOT list around k3s config, PVs, and manifests.
- infrastructure/OS_UPDATE_ROUTINE.md: describes the weekly Paperclip
routine (Sun 03:00 Europe/Berlin) that fires this procedure.
- infrastructure/scripts/os-update/: cluster-health.sh, update-node.sh,
os-update.sh, README. Enforces the same guardrails in code:
workers-first-then-CP, one node at a time, no --force drains, halts on
reboot/kubelet/health failure, never touches k3s config.
