// Heuristik für die Watcher-Loop: server-side Änderungen brauchen
// Process-Restart (Bun cached Module-Imports), Client-Side reicht
// Hot-Reload, Tests/non-TS sollen den Watcher gar nicht triggern.
// Wenn die Klassifikation drift bekommt, kommen entweder unnötige
// Restarts (DX schlecht) oder echte Schema-Änderungen schlagen
// nicht durch (UX broken). Beide sind teuer — daher pinnen wir.
