CLI tool and programmatic API for automated OAuth setup across cloud platforms

/**
 * GCP Setup OAuth command.
 *
 * This command assumes that the root admin user in GCP has already
 * successfully executed the `gcp-setup-service-account` command.
 * The GCP service account credentials will have been saved in the
 * `GCP_OAUTH_APPLICATION_CREDENTIALS` environment variable and those
 * credentials will be used by this command to create and configure
 * the GCP OAuth2 Client.
 *
 * ===========================================================================
 * CRITICAL REQUIREMENT: This script MUST run without ANY user interaction
 * ===========================================================================
 * - The script must be fully automated from start to finish
 * - No manual steps or user intervention should be required
 * - No prompts or questions should be shown
 * - Errors must be handled gracefully with automated fallbacks
 * - Must result in a complete, working setup or clear error message
