Fix the issue with message dispatcher and channels

Resolved a previous error where each subscription would create a new
channel with the fixed buffer size. This caused blocking when the
channel buffer was full, preventing the client from handling additional messages.

Now, there is a `subscriptions` struct that holds a queue for receiving
notifications, ensuring the notify function does not block.
