Add XML doc comments to public properties across EventTypes, Connz, Varz, NatsOptions, StreamConfig, IStreamStore, FileStore, MqttListener, MqttSessionStore, MessageTraceContext, and JetStreamApiResponse. Fix flaky tests by increasing timing margins (ResponseTracker expiry 1ms→50ms, sleep 50ms→200ms) and document known flaky test patterns in tests.md.
