## Bug Fixes
- Fixes a build error when a Markdown content collection entry loaded with `glob({ deferRender: true })` has a `layout` frontmatter property. `layout` is now ignored for content collection entries, as documented.
- Fixes `astro add cloudflare` failing to install dependencies with pnpm v11+ by approving the `workerd` build script, and shows the package manager's error output when `astro add` fails to install dependencies
- Fixes an issue where AVIF images were served as `image/heif` instead of `image/avif` in the dev server.
- Fixes the `cache()` handler from `astro/hono` and `astro/fetch` throwing a `TypeError` when a cache provider is configured. It now registers the cache provider before rendering, so `Astro.cache` is available to downstream handlers like `pages()`.
- Fixes `security.checkOrigin` rejecting cross-origin requests with non-form content types such as `application/json`. As documented, the check only applies to unsafe requests that have no `content-type` header or one of `application/x-www-form-urlencoded`, `multipart/form-data`, or `text/plain`.
