What is the purpose of the hydrate() lifecycle hook

When a Livewire component is first loaded, the `mount()` hook is called to initialize the component. However, on subsequent requests, the `hydrate()` hook is called instead of `mount()`[1].

The `hydrate()` method is useful for:

- Initializing properties that are not persisted between requests[1]
- Performing additional setup or logic that needs to run on every request[2]
- Handling data that is passed to the component via the URL or query string[3]

Here's an example of using the `hydrate()` hook to initialize a property:

php
class ShowPost extends Component
{
    public $postId;
    protected $post;

    public function hydrate()
    {
        $this->post = Post::find($this->postId);
    }
}

In this example, the `$post` property is initialized in the `hydrate()` hook, ensuring it is set up correctly on every request[1].

The `hydrate()` hook is called after the component is instantiated and before any actions are performed or the `render()` method is called[3]. This makes it a convenient place to perform setup tasks and prepare the component for rendering and handling user interactions.
