Replace the static host list with dynamic discovery: workstation (nixos)
and pve1 are hard-wired first and second; remaining hosts are discovered
on every run by SSHing to pve1, listing running VMs/containers via
pct/qm list, and resolving their NixOS hostnames from a single flake eval.

Runs nix-collect-garbage -d on all deployed NixOS hosts and pve1 in
parallel, skipping nix-cache to avoid evicting shared cache paths.
