Description

This PR moves the docs site to Node 26 and updates its dependencies to their latest releases.

• Node 24 -> 26.12.1 in website/oku.toml, website/oku.lock and engines. The website workflow takes Node from website/oku.toml, so it needs no change.
• astro 7.3.7 -> 7.4.2, @astrojs/starlight 0.42.5 -> 0.42.7, @astrojs/markdown-remark 7.3.2 -> 7.3.4, @astrojs/check 0.9.10 -> 0.9.12.
• The postcss-selector-parser override 7.1.6 -> 7.1.7.
• Transitive dependencies refreshed within their ranges.

The lockfile resolves zod 4.6.7, undici 8.12.3 and fast-uri 3.1.9, all past the versions the 8 open Dependabot alerts on website/package-lock.json name, and npm audit reports 0 vulnerabilities.

TypeScript stays on 6.0.3. 7.0.2 is out, but @astrojs/check 0.9.12 only accepts ^5.0.0 || ^6.0.0.

Tested on Node 26.12.1 with a clean npm install, then npm run check (0 errors, 0 warnings) and npm run build (21 pages).
