/**
 * Resolve credentials for install flow.
 * Priority: existing creds (env var, --api-key, active env) -> unclaimed env provisioning -> login fallback.
 *
 * The installer needs both API credentials (for WorkOS API calls) AND gateway auth
 * (for the LLM agent). This function ensures both are available:
 * - Unclaimed env: API key + claim token (claim token proxy handles gateway)
 * - Logged-in user: API key + OAuth token (credential proxy handles gateway)
 * - Direct mode: not handled here (resolved in agent-interface.ts via ANTHROPIC_API_KEY)
