Astro v6.4.2

Descripción Detallada

Patch Changes - #16889 `b94bcfd` Thanks @Princesseuh! - Fixes a `plugins is not iterable` crash when using a pre-6.0 `@astrojs/mdx` alongside integrations (e.g. Starlight) that set `markdown.remarkPlugins`, `markdown.rehypePlugins`, or `markdown.remarkRehype`. - #16878 `b9f6bb9` Thanks @fkatsuhiro! - Fixes an issue where on-demand (SSR) dynamic routes would return 404 when a prerendered dynamic route with the same URL pattern was sorted first alphabetically. In production builds with `@astrojs/node` adapter, if `[aprebuild].astro` (prerender=true) came before `[bssr].astro` alphabetically, requests to URLs not in the prerendered route's static paths would 404 instead of falling through to the SSR route. The fix adds fallthrough logic so that when a prerendered dynamic route matches but can't serve the request, Astro tries subsequent matching routes.
