#15891 b889231 Thanks @matthewp! - Fix dev routing for server:defer islands when adapters opt into handling prerendered routes in Astro core. Server island requests are now treated as prerender-handler eligible so prerendered pages using prerenderEnvironment: 'node' can load island content without 400 errors.

#15890 765a887 Thanks @matthewp! - Fixes astro:actions validation to check resolved routes, so projects using default static output with at least one prerender = false page or endpoint no longer fail during startup.

#15884 dcd2c8e Thanks @matthewp! - Avoid a MaxListenersExceededWarning during astro dev startup by increasing the shared Vite watcher listener limit when attaching content server listeners.

#15904 23d5244 Thanks @jlukic! - Emit the before-hydration script chunk for the client Vite environment. The chunk was only emitted for prerender and ssr environments, causing a 404 when browsers tried to load it. This broke hydration for any integration using injectScript('before-hydration', ...), including Lit SSR.

#15933 325901e Thanks @ematipico! - Fixes an issue where <style> tags inside SVG components weren't correctly tracked when enabling CSP.

#15875 c43ef8a Thanks @matthewp! - Ensure custom prerenderers are always torn down during build, even when getStaticPaths() throws.

#15887 1861fed Thanks @ematipico! - Fixes an issue where the build incorrectly leaked server entrypoint into the client environment, causing adapters to emit warnings during the build.

#15888 925252e Thanks @matthewp! - Fix a bug where server:defer could fail at runtime in prerendered pages for some adapters (including Cloudflare), causing errors like serverIslandMap?.get is not a function.

#15901 07c1002 Thanks @delucis! - Fixes JSON schema generation for content collection schemas that have differences between their input and output shapes.

#15882 759f946 Thanks @matthewp! - Fix Astro.url.pathname for the root page when using build.format: "file" so it resolves to /index.html instead of /.html during builds.
