/**
 * Regenerate `catalog.json`: metadata from models.dev's `hyper` entry, membership and this

 *
 *   npm run regen          write the catalog
 *   npm run regen -- --dry print it without writing
 *
 * Two requests, no probing. Models.dev carries what Hyper's endpoints only partly report
 * (the reasoning effort levels the deployment takes, vision, limits), and `/v1/models`
 * is authoritative for which models exist and what this key is billed.
