Replace stub tests in JetStreamTests.cs and JetStreamConsumerTests.cs with real implementations. Tests that can be verified via the JetStream wire API (NATS.Client.Core + $JS.API.*) are implemented using IAsyncLifetime with NatsConnection; tests requiring Go server internals, server restart, or JetStream clustering remain deferred with descriptive skip reasons.
