/**
 * Mode-compatibility boot smoke test (issue #341).
 *
 * For each non-cloud DEPLOYMENT_MODE, proves the boot path resolves:
 *   1. env validation     — the canonical minimal env satisfies the registry
 *   2. factory resolution — getDeployment() returns the expected mode
 *   3. auth initialization — createAuth() constructs with the mode's options
 *
 * This guards the getcito-cloud build-out: open-source, demo, and whitelabel
 * deployments must keep booting unchanged while cloud lands (issue #8).
 *
 * Runs the real shared-package boot path via tsx — no build, no live DB.
 * createAuth() only constructs the better-auth instance (drizzle's pg pool is
 * lazy), so a dummy DATABASE_URL is enough.
 *
 * Lives in apps/web because that package depends on every @workspace/* package
 * this script boots; the script itself imports only @workspace/* entrypoints
 * (never apps/web's @/ alias), so tsx resolves it with no app bundling.
 *
 * Usage (from repo root):
 *   pnpm -C apps/web exec tsx scripts/smoke-deployment-mode.ts            # all modes
 *   pnpm -C apps/web exec tsx scripts/smoke-deployment-mode.ts whitelabel # one mode
 *
 * Cloud is intentionally skipped: the factory throws "not yet implemented"
 * and ENV_REQUIREMENTS.cloud is empty until #342.
