feat: use config.kit.paths.base for static assets

fixes #4442, fixes #2843 - add manifest.prefix and builder.getAppPrefixDirectory() - adapter-cloudflare*: use manifest.prefix instead of manifest.appDir - adapter-netlify: use prefixed appDir for cache headers - adapter-vercel: use prefixed appDir for routes.json - adapter-cloudflare, adapter-cloudflare-workers, adapter-netlify: write static assets to "$dest/$base"
