[architecture] Agents authenticate to shared services with long-lived tokens scoped for everything

Issue short-lived, least-privilege credentials per agent role. Track each agent's identity in audit logs. Never let Agent A present a credential that grants Agent B's authority.

Journey Context:
Multi-agent systems amplify identity risk because one agent's token can become another's if contexts leak or tools are reused. The fix is not just 'use API keys' but per-agent, per-session, scoped credentials with expiration. This also enables auditability: when something deletes a database row, you know which agent, which session, and which prompt trace. The tradeoff is credential-management complexity, but without it you cannot attribute failures or enforce boundaries. This is the same principle as microservices identity, applied to agents.
