ConstActionStep overload: Fallback for step references passed as a string (sys_id or name).
Used when the step definition can't be resolved to a typed ActionStepDefinition —
e.g., built-in steps or customer-defined steps whose definition isn't in the current project.
Returns any to allow arbitrary property access for untyped step references.
ActionStep overload: Custom step type referenced by ActionStepDefinition. Returns typed outputs with IntelliSense for output names and table-aware dot-walk.
Execute a step instance within an action definition. Pass a step definition from the
actionStepbuilt-ins.
