Beenvoice repository guidance

Use Bun exclusively for dependency installation and workspace scripts.
Run cross-workspace commands from the repository root; use --filter for app-specific tasks.
Put platform-neutral rules, serialized types, constants, and parsing in packages/domain.
Keep browser-only UI in apps/web and React Native/native code in apps/mobile.
Do not import server implementations into mobile runtime bundles. The AppRouter import is type-only.
Keep Drizzle migrations and their journal together under apps/web/drizzle.
Never commit .env, signing credentials, native build output, receipts, or customer data.
