SiriusResult can only wrap subclasses of RuntimeException

This might be overly restrictive, especially since (for example) IOException is not a subclass of RuntimeException. Is there a reason SiriusResult can't just wrap Exception? I get that RuntimeException is the superclass of unchecked exceptions, but it's not obvious to me if or why that would be relevant.

Start by locating SiriusResult and inspecting how its current RuntimeException restriction is defined and used. Determine whether wrapping broader exceptions such as IOException is intended, then verify that the chosen behavior is covered and that existing exception handling remains consistent.
