Both earlier versions asked the wrong host. `hyperhive.otel.enable` asked
whether this host runs a HIVE collector; `deploy.swarm-otel.enable` asked
whether this host runs the SWARM one. Neither answers the question the
forwarder actually has — "is there a collector to forward to" — and that
question cannot be false: a swarm always runs at least one instance of
every swarm-level service. So the forwarder renders under the condition
already enclosing it, that the store is deployed here, and nothing else.
`scrapeHere` deliberately keeps its `deploy.*` gate one line up. It is a
loopback metrics listener, which genuinely only works where the scraper
is — the two are different tiers, and the name says so.
The module-eval case that pins it is the split topology: the swarm
collector on another host, nothing local naming it, and the forwarder
still enabled and still addressed at `swarm.otel.domain`'s route. Both
removed gates render nothing in that fixture, which the co-located ones
they shipped with could not show.
