fix(container): survive a Docker daemon restart
A user container was created with no restart policy, so anything that
stops the daemon stopped it for good — an `apt upgrade` pulling a new
docker-ce SIGTERMs every container (exit 143) and only those carrying a
policy come back. Skald's own process survives that, and `ensure()` runs
only at boot, at login and off the lifecycle bus, so nothing noticed:
every `docker exec` path then failed identically until someone logged in
again. The per-user MCP servers respawn-looped on `container ... is not
running`, and a connector's dependency install failed with the same line.

Create with `--restart unless-stopped`, and reconcile an existing
container's policy in place with `docker update`. `unless-stopped` rather
than `always` because `stop_all()` stops these deliberately at shutdown:
the flag Docker sets there is exactly the one this policy honours, so a
daemon restart while Skald is down leaves them alone and the next boot's
`ensure` starts them.

The in-place reconcile is deliberately not a sixth `reusable()` axis. The
policy is the one property Docker can change on a live container, so
making it a recreate would throw away a running container — and every
`docker exec` under it — to set a flag.
