[Drones][M5.4] Demote lesser-host portal-only entry points in favor of the agent-first Simulacrum flow

[aron23]

Parent Milestone

[Drones][M5] Verify, document, and roll out the agent-first FaceTheory soul flow

Step

Demote or retire lesser-host portal-only soul creation entry points so they are no longer presented as the canonical user-facing path once the rewritten client supports the flow.

Completion Criteria

• the portal is no longer implied to be the canonical UX
• any remaining portal-only entry points are explicitly secondary, deprecated, or gated
• the parent milestone no longer depends on conflicting guidance across surfaces
