/**
 * Z.ai / GLM OAuth flow (GLM Coding Plan · Sign in)
 *
 * Mirrors ZCode's desktop "Individual Plan" browser sign-in: an
 * authorization-code flow (no PKCE) against chat.z.ai, a JSON token exchange
 * that yields a short-lived OAuth access token, and a business-API sequence
 * that provisions a durable `id.secret` API key. The minted key is placed in
 * {@link OAuthCredentials.access}; `getOAuthApiKey` returns it verbatim as the
 * request bearer for the `zai` provider, so no dialect change is needed.
