    Skip SSR build for fully static Cloudflare sites (#16468)
    
    * Skip SSR build for fully static Cloudflare sites
    
    - Cloudflare adapter now passes through buildOutput from core instead of
      hardcoding 'server', allowing static sites to skip the SSR environment build.
    - Server islands plugin upgrades buildOutput from 'static' to 'server' when
      server:defer components are discovered during prerendering.
    
    * Use @cloudflare/vite-plugin pre-release from PR #12788
    
    Adds minimumReleaseAge exclusions for transitive Cloudflare deps.
    
    * Fix: upgrade buildOutput after prerender build, not during it
    
    Move server islands buildOutput upgrade from the vite plugin transform
    (which runs mid-prerender-build) to static-build.ts (after prerender
    completes). This avoids a directory path mismatch where the prerender
    output is written to the static path but manifest injection writes to
    the server path.
    
    * Fix: detect server islands via plugin API, mutate buildOutput after prerender
    
    - Expose hasServerIslands() on server islands plugin API
    - After prerender build, upgrade buildOutput to 'server' if server
      islands were discovered (so SSR build, manifest injection, and
      runtime all use correct server paths)
    - Capture prerenderOutputDir before mutation to avoid path mismatch
    - Simplify writeMutatedChunks to use getServerOutputDirectory
    - Update session wrangler config test for static build output path
    
    * Add preserveBuildServerDir, stop mutating buildOutput in static-build
    
    - Add preserveBuildServerDir adapter feature so adapters can control
      the server output directory for static builds (mirrors preserveBuildClientDir)
    - Cloudflare adapter sets preserveBuildServerDir: true
    - Extract hasServerIslands() from server islands plugin as a standalone
      exported function that accepts any BuildEnvironment
    - Replace buildOutput mutation in static-build.ts with a needsServerBuild()
      helper that checks settings.buildOutput or hasServerIslands()
    
    * Fix server islands guard to check for adapter, not buildOutput
    
    * Fix preview for static sites with SSR routes and internal route handling
    
    - Stop overwriting buildOutput after route scanning in preview command;
      let route scanning upgrade it from 'static' to 'server' when needed
    - Skip static preview server when adapter provides a previewEntrypoint
    - Use getClientOutputDirectory in static preview server to respect
      preserveBuildClientDir
    - Exempt internal routes (e.g. server islands) from getStaticPaths
      requirement and static path matching
    
    * Fix no-shadow lint error in server islands plugin
    
    * Add changesets for astro and cloudflare
    
    * Update astro changeset to minor with adapter usage example
    
    * Use @cloudflare/vite-plugin devOnly to skip SSR build for static sites
    
    Switch to @cloudflare/vite-plugin PR #13985 which adds a devOnly property.
    Set devOnly to a function that returns true when buildOutput is 'static',
    letting the CF plugin skip the SSR worker build and emit an assets-only
    wrangler config for fully static sites.
    
    * Update lockfile for @cloudflare/vite-plugin ^1.39.0
    
    * Update pnpm-workspace.yaml
