#16723 0f10bfe Thanks @matthewp! - Adds FetchState.response property, set automatically after pages() or middleware() completes

#16723 0f10bfe Thanks @matthewp! - Adds Fetchable type export for typing the advanced routing entrypoint

#16572 4a5a077 Thanks @DORI2001! - Suppresses [WARN] Vite warning: unused imports from "@astrojs/internal-helpers/remote" during prerender builds. The package is now bundled alongside astro in the prerender environment, matching how it is handled in the SSR environment.
#16756 b6ee23d Thanks @astrobot-houston! - Fixes styles from Markdoc/MDX custom components not being extracted to <head> in the dev server when using the Cloudflare adapter with prerenderEnvironment: 'node' and rendering content through a wrapper component.
#16747 904d19a Thanks @astrobot-houston! - Fixes Astro action requests failing in astro dev when using the Cloudflare adapter with prerenderEnvironment: 'node' alongside a prerendered catch-all route such as [...page].astro.

Actions and other SSR POST endpoints now continue to work in dev instead of returning an HTTP 500 error.
#16701 3495ce4 Thanks @demaisj! - Fix Map and Set instances saved in a content collection being broken when retrieving entries.
#16614 fca1c32 Thanks @Eptagone! - Fixes entry.data type inference when a live collection is configured without a schema.

#16681 c22770a Thanks @dotnetCarpenter! - Fixes an issue where SVG images with width="0" or height="0" incorrectly threw a NoImageMetadata error instead of being treated as valid dimensions.
