feat: agent roleUniversalIdentifier for manifest-driven role assignment (#23206)

## Summary
- Adds optional `roleUniversalIdentifier` on `AgentManifest` /
`defineAgent` so apps can declaratively assign a role to an agent (same
config shape as `defaultRoleUniversalIdentifier`).
- Wires `agentUniversalIdentifier` as a sync many-to-one FK on
`roleTarget`, and emits a deterministic `roleTarget` from the agent
during app sync (create / update / delete).
- Enables app agents (e.g. Slack assistant) to get a role on install
without postInstall hooks or manual admin assignment.
