New specialized agent: Identity Graph Operator - operates a shared identity
graph so multiple agents in a system all resolve to the same canonical entity.
Prevents duplicate records, conflicting actions, and cascading errors when
agents encounter the same real-world entity from different sources.
New example workflow: Multi-Agent Shared Identity - step-by-step walkthrough
of 3 agents (Support, Backend, Analytics) handling the same customer across
email, phone, and web channels with shared identity resolution.
Enhanced Agentic Identity & Trust Architect with a section showing how it
complements the Identity Graph Operator (agent identity vs entity identity).
