- Eagerly create AI and user peers in Honcho when a profile is created
  (not deferred to first message). Uses idempotent peer() SDK call.
- hermes honcho enable: turn on Honcho for active profile, clone
  settings from default if first time, create peer immediately
- hermes honcho disable: turn off Honcho for active profile
- _ensure_peer_exists() helper for idempotent peer creation
