/**
 * Hard-delete every persona known to the catalog.
 *
 * Wipes the user row (cascades through personas, persona_actions,
 * persona_feedback, sessions, vault, organizations the user owns alone,
 * and downstream sync data). Useful after iterating on the catalog or
 * before a fresh seed run.
 *
 * Refuses to touch any user where kind != 'persona' (the admin endpoint
 * enforces this server-side too — defense in depth).
 *
 * Usage:
 *   pnpm seed:personas:cleanup
 *   pnpm seed:personas:cleanup --auth=https://auth.mana.how --jwt=eyJ…
