* Skip deploy previews for fork PRs that lack Cloudflare secrets
Fork PRs don't have access to repository secrets (CLOUDFLARE_API_TOKEN,
CLOUDFLARE_ACCOUNT_ID), so deploy/smoke-test/comment steps always fail.
Add a fork detection condition to skip these steps gracefully. The build
steps still run, so example builds are still validated for fork PRs.
* fix: align Pages Router worker entry with prod-server request handling
The generated Cloudflare Worker entry for Pages Router apps was missing
several request handling steps that the Node.js production server
(prod-server.ts) already handled. This brings the two in sync:
- Run middleware (runMiddleware) before routing
- Apply next.config.js redirects, rewrites (before/after/fallback), and headers
- Handle basePath stripping and trailing slash normalization
- Merge middleware response headers with correct precedence
- Guard renderPage with typeof check
Also updates the two Pages Router examples (pages-router-cloudflare,
realworld-api-rest) and exports vinext/config/config-matchers so the
worker entry can import the shared matching utilities.
* chore: sync pnpm-lock.yaml with upstream package.json changes
