tailscaled is waited for before tailscale up, a tailscaled that already runs on
the runner is not taken over and down leaves a daemon it did not start, sudo is
used only when the job is not root, an exact version is required to install
(with an optional sha256 of the archive), and the guide states when the node is
ephemeral and calls @main until the release.

Task: MIL-012#4
The wireguard-go choice now survives sudo (it is passed through env), sudo is
used only when the job is not root, a configuration field with a line break is
refused, only the key values of a full configuration are masked, the key file
is removed when wg-quick fails, and the guide calls @main until the release.

actions/connect-tailscale joins a Tailscale network for a deployment job, with
a guide and offline tests. Whether tailscaled survives to the next step is
still open (MIL-012 task 4).

actions/connect-wireguard brings a WireGuard tunnel up for a deployment job and
takes it down again, with a guide and offline tests. The runs on a real runner
(MIL-012 task 3) are still to do.
