/**
 * Model catalog for the `codex-pool` provider.
 *
 * Registering a provider without a `models` array leaves it with an empty
 * catalog: senpi's `applyExtension()` replaces a provider's model list with
 * whatever the extension supplies, and an extension-registered provider id has
 * no built-in catalog to inherit. The provider then registers "successfully"
 * but exposes zero models, so `--provider codex-pool` fails with
 * `Unknown provider`.
 *
 * These mirror stock `openai-codex` so pooling changes only which account
 * serves a request, never which models exist or how they are priced. Costs are
 * per-million tokens, matching stock's catalog.
