- reconciler: a deleted current-stage board task no longer wedges the pipeline
in 'running' forever (terminality computed over existing tasks only; all-deleted
is a no-op, not a wedge)
- session-store: a human-slow awaiting_input session is no longer misclassified
stale (interval rubric applies only to in-flight active/launching turns)
- stage-registry: pipeline progression uses an explicit order ordinal instead of
registry insertion order, so out-of-order registration can't corrupt advancement
- orchestrator.answer(): validate questionId before mutating state, so a stale id
can't destroy the persisted currentQuestion recovery anchor
- orchestrator.resume(): rehydrate a live interactive session by replaying
persisted history (side effects suppressed) so a resumed session is actually
answerable instead of dead-ending; honest interrupted+error fallback when no
factory is available
