/**
 * Test-Runner: führt alle `scripts/test-*.ts` nacheinander via tsx aus und liefert eine
 * Zusammenfassung + Exit-Code (≠ 0, sobald ein Test scheitert).
 *
 * Voraussetzungen: lokale Infra (Postgres/Redis/Garage) läuft, `.env` gesetzt, Datenbank
 * migriert und geseedet (`npx prisma migrate deploy && npx prisma db seed`).
 *
 * Lauf:  npm run test                  (alle)
 *        npm run test -- mail tenant   (nur Tests, deren Name einen der Filter enthält)
