fix(feishu): register no-op handlers for reaction events (#140)

The Feishu SDK EventDispatcher had no handler registered for im.message.reaction.created_v1 / deleted_v1, so adding or removing an emoji reaction raised HandlerNotFoundException and logged an ERROR stack trace. Register no-op handlers to silently ignore these events.
