## Cambios principales:

1. **Reemplacé `Watch` por `effect`** (25 líneas, estilo Sigwork)
2. **Añadí `watch` como helper** (12 líneas, con untrack automático)
3. **Misma seguridad de memoria** (scopes anidados, cleanups automáticos)
4. **Misma eficiencia** (queueMicrotask, scheduling)
5. **Todo el resto de SigPro intacto** (Router, For, If, Tag, etc.)

## Uso:

```javascript
// Effect automático (como Sigwork)
effect(() => {
  console.log(count(), user().name, theme());
  // Suscribe a todo lo que lees
});

// Watch específico (con untrack automático)
watch(count, (newVal, oldVal) => {
  console.log(newVal, oldVal);
  // Solo suscribe a count
});

// Router sin re-renders
watch(currentPath, (path) => {
  updateRoute(path); // No causa re-renders del componente padre
});
```
