The `pubsub` facade now selects gossipsub by default. This is a pre-1.0 behavior change: `EndpointBuilder::pubsub_config` accepts either `GossipsubConfig` or `FloodsubConfig` through `PubsubConfig`; applications that require the old engine must pass `FloodsubConfig::default()` explicitly. Each engine advertises only its own protocol IDs, so mixed gossipsub/floodsub endpoints intentionally do not exchange pubsub traffic.
