Scaffold docs/site/ via `npm create astro@latest ... --template starlight`. Extend the docs collection schema in src/content.config.ts with the four custom frontmatter fields (man, site, manTitle, helpKeywords) needed by the generator in a later task, using z.strictObject so unrecognized keys fail the build instead of being silently stripped by Zod's default behavior. Ignore generated site output (node_modules, dist, .astro, generated content, and sidebar.json) in .gitignore.
