Subject: [PATCH 1/2] Fix NotificationHandler for Node 24 Lambda runtime

The wrapped SNS handler declared a 3-argument `(event, context, callback)`
signature. Node 24's Lambda runtime rejects callback-style handlers at
init with `Runtime.CallbackHandlerDeprecated`, even when the callback is
never invoked.

Drop the callback parameter and let promise rejection propagate, which
matches what the other handler wrappers in this package already do.

Fixes #58.
