描述

Currently if no callback is supplied for the event, nothing happens, and firing the event returns nil.

It might be handy be able to supply a default action.

i.e. fires save: :default_save_method

currently you can work around this by checking props[event_name] for nil

研究方向
Explore the event system in Hyperstack by examining where events are defined and fired. Look for the `fires` method implementation and the code that checks `props[event name]` to understand the current behavior. Then design a solution to allow a default callback as a second argument to `fires`. Consider backward compatibility and the workaround mentioned in the issue.
