/**
 * session runtime's ModelRegistry/AuthStorage expects credentials in auth.json.
 *
 * OpenClaw stores credentials in auth-profiles.json instead. This helper
 * bridges all credentials into agentDir/auth.json so session runtime can
 * consider provider-owned configured models authenticated.
 *
 * Syncs all credential types: api_key, token (as api_key), and oauth.
 *
 * @deprecated Runtime auth now comes from OpenClaw auth-profiles snapshots.
