Document the end-state auth/authz model unifying the three services
around a bearer → resolved library set abstraction. Replaces the
per-turn JWT forwarding scheme with static team JWTs held by Pallas
deployments, eliminating custom transport code and the monkey-patch
chain that caused opaque failures in agent teams.
Also records the UX shift where Daedalus workspaces attach Teams
(Pallas instances) rather than individual agents.
