* Replace Nats with Nats Jestream For PubSub Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add Stream Description Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Fix connection leak in NATS publisher The publisher struct in pkg/messaging/nats/publisher.go was modified to include a new `conn` field of type `*broker.Conn`. This change was made to fix a connection leak issue in the NATS publisher. The `NewPublisher` function was updated to assign the `conn` parameter to the new `conn` field in the publisher struct. Additionally, the `Close` method in the publisher struct was modified to close the `conn` connection. This commit fixes the connection leak issue in the NATS publisher and ensures that connections are properly closed.
