Bug: Astro Integration Packages Lag Behind Version

Astro was upgraded to a new major version (5.x), but its integration packages (@astrojs/check, @astrojs/react, @astrojs/svelte, @astrojs/vue) were not updated. These packages are likely incompatible with Astro 5.x, which may cause build failures or runtime errors.
