Bare openclaw does not open Crestodian once config has authored settings.
Document the actual three-way routing: missing/unauthored config starts
classic onboarding, invalid config starts Crestodian for repair, valid
config opens the normal agent TUI (local or reachable configured Gateway),
with /crestodian or openclaw crestodian as the explicit entry points.
