test: accept 'review mode = X' auto-decide declarations and parenthetical scope exclusions in the shared-libs actor

auto-decide-preserved: the product auto-decided HOLD SCOPE and said
"Decision: review mode = HOLD SCOPE"; the grammar knew only "is" and ":".
shared-libs-plan-callers: the recommended option said "(no hardening)" and the
actor read "hardening" as an expansion. Both replay the captured text, keep
negative controls, and passed focused paid runs.
