Identity as a lifecycle, not a setting

What this post added

Introduces the concept of agent identity as a lifecycle, moving beyond static settings to dynamic management. Proposes just-in-time (JIT) credential provisioning and programmatic revocation as key mechanisms to eliminate standing privilege. Highlights the operational feasibility of JIT access for agents compared to humans and references OpenID Provider Commands for identity lifecycle operations (activate, suspend, revoke, delete). Emphasizes continuous runtime authorization evaluation tied to the agent's task.
