manifests: raise global controller floor 0.113.0 → 0.120.0 (publish train)

Env fallback DEFAULT_MIN_CONTROLLER_VERSION for the CAMPAIGN-3 wave. Day-0
artifact manifest already vouches agent 0.85.0 + golden 0.120.0 (MinAgent
0.81.0). Demo already 0.120.0 (no churn); Peti offline + gated (agent 0.79 <
MinAgent 0.81 → controller held at 0.113 until his agent lands). DB global
floor to be aligned to 0.120.0 by the operator, saved last.
