## Summary

- Closes https://github.com/tailwindlabs/tailwindcss/issues/19744
- Closes https://github.com/vitejs/vite-plugin-react/issues/1118
- Closes https://github.com/wakujs/waku/issues/1963

The change in https://github.com/tailwindlabs/tailwindcss/pull/19670
didn't take account for server only modules managed by SSR framework.
Forcing full reload for this path breaks server HMR. This PR added a
check to determine whether the same modified file has associated modules
in a different environment module graph to avoid this.

## Test plan

<!--

Explain how you tested your changes. Include the exact commands that you
used to verify the change works and include screenshots/screen
recordings of the update behavior in the browser if applicable.

-->

Added an integration test for React router HDR (server loader hmr). This
test fails on main.

Also the local build is tested on `@vitejs/plugin-rsc` CI and confirmed
the fix https://github.com/vitejs/vite-plugin-react/pull/1132
