Terminate registered agent.
End a registered-agent contract. Used during dissolution (after Certificate of Dissolution acceptance) and when switching providers. The dissolve cascade calls this verb once per attached registered agent after Certificate of Dissolution acceptance, giving the founder a typed audit trail.
Tier-3 token. When reason = switching_provider, a superseded_by_id pointing at the new RegisteredAgent is required; on dissolution, leave it null.
