interceptor
Register an interceptor to observe and potentially veto saga step execution.
Interceptors are invoked before and after each step (StepPhase.Before → StepPhase.After, LIFO for After), and after each compensation action (StepPhase.Compensation). An interceptor returning InterceptorOutcome.Veto from a StepPhase.Before phase prevents the step from executing and initiates compensation of prior completed steps.
Registration order matters — see SagaInterceptor for ordering semantics.
