chore: upgrade Astro 6 beta to stable

Move from astro@6.0.0-beta.17 to astro@^6.0.4 (stable) and centralize
the version in the pnpm catalog. Also upgrades Astro integrations from
beta to stable: @astrojs/react 5.0.0, @astrojs/alpinejs 0.5.0, and
@astrojs/partytown ^2.1.5.

Fixes build test to handle Astro 6 stable's chunk output structure where
multiple index_*.mjs chunks may exist in server builds.
