###### Add `@vitejs/plugin-react/preamble` virtual module for SSR HMR ([#890](https://github.com/vitejs/vite-plugin-react/pull/890))

SSR applications can now initialize HMR runtime by importing `@vitejs/plugin-react/preamble` at the top of their client entry instead of manually calling `transformIndexHtml`. This simplifies SSR setup for applications that don't use the `transformIndexHtml` API.

###### Fix raw Rolldown support for Rolldown 1.0.0-beta.44+ ([#930](https://github.com/vitejs/vite-plugin-react/pull/930))

Rolldown 1.0.0-beta.44+ removed the top-level `jsx` option in favor of `transform.jsx`. This plugin now uses the `transform.jsx` option to support Rolldown 1.0.0-beta.44+.
