/**
 * Seed the persona catalog into mana-auth.
 *
 * Idempotent: re-running upserts metadata, never duplicates users. New
 * personas in catalog.json get registered; existing ones get their
 * descriptor refreshed.
 *
 * Requires:
 *   - mana-auth running (default http://localhost:3001)
 *   - An admin-tier user JWT (export MANA_ADMIN_JWT or pass --jwt=…)
 *   - PERSONA_SEED_SECRET in env (or accept the dev fallback locally)
 *
 * Usage:
 *   pnpm seed:personas
 *   pnpm seed:personas --auth=https://auth.mana.how --jwt=eyJ…
