useEffect does not re-fire on hot reload with React 19

Describe the bug

Original issue filed here: https://github.com/vitejs/vite-plugin-react/issues/426, also applies to this plugin.

In prior versions of react, saving a file will trigger the components useEffect hooks to run. This does not work for react 19.

Validations

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a Vite issue and not a framework-specific issue.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Start with the linked reproduction and follow the listed steps, especially switching between @vitejs/plugin-react-swc and @vitejs/plugin-react in vite.config.ts. Compare hot-reload behavior under React 19; done means saving a file causes the affected component's useEffect hooks to run as they did in prior React versions.
