Supervision invariants (SV-*)

• SV-1 (root-cause attribution): For an UnhandledSupervisionEvent chain, actually_failing_actor() returns the event that should be treated as the root cause for structured failure attribution. In particular, if a failed parent wraps a stopped child event, the stopped child remains the root cause.
