Apply output mapping after subflow completion.
Writes mapped values back to parent scope using merge semantics:
arrays are appended, objects are shallow-merged, scalars are replaced.
Redaction: every write here goes through parentContext's write funnel,
which asks the run's redaction rule — so a policy-redacted or per-call
marked key lands in the PARENT's log and mirror as the placeholder (9.19.0).
