v0.19.0

Puck 0.19 introduces the [Slots API](https://puckeditor.com/docs/api-reference/fields/slot) for nesting components using fields, along with major performance optimizations, a new metadata API, and various quality-of-life improvements.

Read the Puck 0.19 [release post](https://puckeditor.com/blog/puck-019) for a list of all the new features, and the Puck 0.19 [upgrade guide](https://puckeditor.com/blog/upgrading-to-puck-019) for upgrading from Puck 0.18.3.

## Summary

- **[Slots API](https://puckeditor.com/docs/api-reference/fields/slot)**: `slot` is a new field type you can use to nest components. Since slots are fields, you can fully leverage APIs like [`defaultProps`](https://puckeditor.com/docs/api-reference/configuration/component-config#defaultprops) and [`resolveData`](https://puckeditor.com/docs/api-reference/configuration/component-config#resolvedatadata-params) to programmatically control nested content.
- **[`walkTree`](https://puckeditor.com/docs/api-reference/functions/walk-tree)**: a utility function for recursively traversing and updating the entire [data payload](https://puckeditor.com/docs/api-reference/data-model/data), or just a single [`ComponentData`](https://puckeditor.com/docs/api-reference/data-model/component-data) node. It can be used to inspect, update, or validate nested components.
- **Metadata API**: inject data into all components in your config without using React context. The injected data is available in both [`render`](https://puckeditor.com/docs/api-reference/configuration/component-config#renderprops) and [`resolveData`](https://puckeditor.com/docs/api-reference/configuration/component-config#resolvedatadata-params).
- **[Selectors for `usePuck`](https://puckeditor.com/docs/api-reference/functions/use-puck)**: subscribe to the parts of the internal [Puck API](https://puckeditor.com/docs/api-reference/puck-api) you need in order to avoid unnecessary re-renders using the [`createUsePuck`](https://puckeditor.com/docs/api-reference/functions/use-puck) factory.
- **[`useGetPuck`](https://puckeditor.com/docs/api-reference/functions/use-get-puck)**: access the latest [Puck API](https://puckeditor.com/docs/api-reference/puck-api) within callbacks without triggering re-renders.
