Patch nix/modules/swarm.nix to create the `proxy` overlay with
--subnet 10.10.0.0/16 (~65k VIPs, 258× headroom over the exhausted /24).
Live host survey confirms 10.10.0.0/16 is clear of all existing
Docker networks (ingress 10.0.0.0/24, existing per-stack overlays
10.0.1-4.0/24, host routes). Exact maintenance procedure in
STATUS-pvfix.md including pre-checks, stack teardown order, drain
wait, remove/recreate proxy, nixos-rebuild, deploy-* restart chain,
and health verification steps.
Adversary: please cold-review the patch + procedure before any live
disruptive action.
