Christian Byrne aef71852f0 feat: add demo pages with Arcade embeds at /demos/{slug} (#11436) ...

*PR Created by the Glary-Bot Agent*

---

## Summary

Adds a demo pages system to the website that embeds Arcade interactive
walkthroughs at `comfy.org/demos/{slug}`. These pages will be linked
from welcome/lifecycle emails via Customer.io.

- Adds `/demos/image-to-video` and `/demos/workflow-templates` as the
first two demos
- Follows the existing `customers/[slug].astro` pattern exactly
(config-driven `getStaticPaths()`)
- Full SEO: OG/Twitter cards, HowTo + LearningResource + BreadcrumbList
JSON-LD schemas
- GEO: AI crawler directives in robots.txt, crawlable transcript
alongside iframe
- A11y: iframe title, sr-only transcript, aria-expanded toggle, noscript
fallback
- Email optimization: 1200x630 OG images, SSG pre-rendered, preconnect
to Arcade CDN
- Full zh-CN localization
- Library index stub at /demos for future expansion
- Automatic sitemap inclusion

## Architecture

Adding a new demo = adding one object to `src/config/demos.ts`.

## Note

OG images are tiny placeholders — replace with real 1200x630 screenshots
before go-live.
