♻️ Refactoriza la API de Children e InRegion

- Patrón prototipo en `InRegion`: cada petición recibe clones profundos.
- `ComponentClone` habilita clonar `dyn Component` de forma segura.
- `ChildTyped<C>` renombrado a `Slot<C>`, elimina `ChildTypedOp`.
- `Mutex` en lugar de `Arc<RwLock>` en `Child` y `Slot`.
- `is_renderable` y `setup_before_prepare` reciben `&Context`.
- Nuevos tests para `Children`, `ChildOp` y `Slot`.
