ci(docs): pin docs build to Node 22.12.0 for Astro 6.4+

[taliesin-ai]

Why

Astro 6.4 dropped Node 20 support — its engines.node is now >=22.12.0 (6.0.0 allowed ^20.19.1 || >=22.12.0). The Cloudflare Pages wails-v3-site docs build has no Node pin, so it runs Cloudflare's default (<22.12.0) and fails the engine check the moment astro resolves to 6.4.x. This is exactly why #5641 (which bumps the docs lockfile to astro 6.4.8) fails its Cloudflare check.

Change

Pin the docs/ build root to Node 22.12.0 via .nvmrc + .node-version (Cloudflare Pages reads either from the project root directory).

Follow-up (dashboard — can't be done in-repo)

If the Cloudflare Pages project has a NODE_VERSION environment variable set in the dashboard, it overrides these files — it should be set to 22.12.0 (or removed so the files take effect). Once this lands, updating #5641's branch should make its Cloudflare build pass.

Poem

🐇 A version is pinned, neat and true,
Node twenty-two, twelve-point-oh new!
The docs hop along on fresh runtime ground,
No mismatched engines to be found.
Carrots for all — the config is sound! 🥕
