`SpatialNavigationNode` isFocusable change is not working.

**Describe the bug**
The SpatialNavigationNode component does not function correctly when the isFocusable prop is changed dynamically.

**To Reproduce**
```tsx
const [focusable, setFocusable] = useState(false);

return (

{() => }

);
```

**Expected behavior**
The component should be able to receive focus when isFocusable is set to true and should not receive focus when it is false.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Version and OS**
- Library version:4.0.1
- React Native version: react-native-web 0.19.13
- OS: web

**Additional context**
I found that adding isFocused as a dependency at this [line](https://github.com/bamlab/react-tv-space-navigation/blob/3c53f44f0b91e06146df0b7c3a9d46f945d8a86b/packages/lib/src/spatial-navigation/components/Node.tsx#L204) resolves the issue. However, I'm uncertain if this is an appropriate solution.

Start in packages/lib/src/spatial-navigation/components/Node.tsx around line 204, where the issue reports that adding isFocused as a dependency resolves the problem. Reproduce the dynamic isFocusable toggle from the report and inspect the surrounding focus logic. Done means the node receives focus when isFocusable becomes true and is excluded when it becomes false.
