Nicolas De LoofandClaude Sonnet 5 b5cf514b29 fix(provider): clean up stale relay and guard start/restart against it
A provider that stops publishing endpoints on a later `up` left its
previously created relay running: deployRelay was only evaluated when
endpoints were non-empty, so a zero-endpoint up fell through with no
cleanup. The generic reconciler is no help either — it returns early
for any service.Provider != nil, before the recreate logic that would
otherwise catch this. runPlugin now removes any existing relay when a
provider publishes no endpoint on an up, whether it never did or
stopped doing so since a previous run.

Separately, startServiceContainer and restartContainer had no
relay-awareness at all, unlike exec/cp which already refuse to target
one via checkRelayTarget. A relay is a shell-less, FROM-scratch binary
standing in for the service on the network: it has no filesystem or
process for secrets/configs injection or PreStart/PostStart/PreStop
hooks to act on. Nothing in the compose-spec schema forbids declaring
secrets, configs or hooks on a provider: service, so this was reachable
in practice, not just in theory. Both now skip those steps for a relay
container while still starting/restarting the container itself
normally.
