fix(deps): patch nitropack so comark plugins stay external on Nuxt 4.6

[larbish]

Fixes the landing page returning 500 FUNCTION_INVOCATION_FAILED since the Nuxt 4.6 upgrade (#55), and adds CI checks so this class of bug fails directly in CI.

Fix

• Nuxt 4.6 hands Nitro absolute paths for SSR imports from layer components (fix(vite): resolve bare ssr externals from their importer nuxt/nuxt#36309).
• Nitro couldn't map a file back to comark's ./plugins/* pattern export, so it bundled comark/plugins/rangi, whose ../utils/index.js import was then emitted as a broken path.
• Replaces the nitrojs/nitro#4651 pkg.pr.new override with registry nitropack@2.13.4 plus one patch: #4651 itself, and the externals fix (to be upstreamed to Nitro v2). Each patched block is tagged [comark-docs patch].

CI

• New e2e Vitest project that boots the built playground and crawls it: every sitemap page and its OG image, plus the agent routes.
• Checks that every import in the server bundle resolves inside .output/server, which covers lazy chunks no route loads.
• Runs after pnpm build, with content pinned to the commit under test.

🤖 Generated with Claude Code, reviewed by @larbish before opening.

Summary by CodeRabbit

• Bug Fixes

  • Improved deployment routing for header-only and redirect routes, and improved resolution of bundled package imports.

• Tests

  • Added end-to-end checks for page and sitemap responses, Open Graph images, markdown responses, and bundled server imports.
  • Separated unit and end-to-end tests; CI now runs end-to-end tests after the build.

it.each(pages) skips both image checks when a docs page has no og:image, so the test passes even though that page calls defineOgImage.

Tip

Set github.draw: on-demand in .github/pr-lens.yml and PR Lens stops drawing pull requests on its own. Comment @pr-lens draw on a pull request when you want that one drawn

🪧 More tips

• Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
• Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists
• Click the link under each diagram to open it on a canvas you can zoom, pan and step through
• The diagrams are links. Click one to open it on the canvas, then press W or click play to walk through the change
• Open a diagram on the canvas, then press W or click play to walk through the change one step at a time
• The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
• Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs as before
• Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works
• After a push, tick Redraw to draw the latest commit
• Switch GitHub to dark mode and the diagrams follow. The moving dots are this pull request's data in motion

📝 Walkthrough

The change patches Nitro route generation and package-export resolution. It adds a Vitest end-to-end project that starts the built playground server and checks bundled imports and routes. CI runs the end-to-end tests after the build.

Changes: Build and end-to-end validation

Layer / File(s)	Summary
Nitro route and export resolution changes patches/nitropack@2.13.4.patch, pnpm-workspace.yaml	The Nitro patch emits header-only Vercel routes separately from redirects and adds matching for pattern exports during external resolution. The workspace applies the patch to nitropack@2.13.4.
Vitest end-to-end project and server setup vitest.config.ts, package.json, test/e2e/setup.ts	Vitest separates unit and end-to-end projects. End-to-end setup starts the built playground server, waits for /robots.txt, provides baseURL, and returns a cleanup function.
End-to-end checks and CI execution test/e2e/*, .github/workflows/ci.yml	The tests check bundled imports, sitemap pages, Open Graph images, agent routes, and markdown responses. CI runs the end-to-end project after the build with GitHub token and branch environment values.
