Pull request overview

Sets up the repository’s initial build/tooling for generating a Doc Kit static site, including a prebuild step that generates a shared navigation/authors config consumed by custom theme components.

Changes:

• Add a config-generation script (prebuild) that fetches nav/i18n/authors and derives sidebar + page author mappings from pages/.
• Add Doc Kit configuration plus custom theme components (Navigation/Sidebar/Metabar) wired via #theme/* imports.
• Add baseline repo tooling/docs: package.json scripts/deps, ESLint flat config, README/CONTRIBUTING.

SGTM! Left tiny comments and the PR title should probably match that it adds the scripts and initial packages and components :)

adding .editorconfig would be great before merging any script 🙏

Also I think we should create learn version of these configs;

• https://github.com/nodejs/doc-kit/blob/main/.prettierrc.json
• https://github.com/nodejs/doc-kit/blob/main/.prettierignore
• https://github.com/nodejs/doc-kit/blob/main/.nvmrc
• https://github.com/nodejs/doc-kit/blob/main/.gitignore
• https://github.com/nodejs/doc-kit/blob/main/.gitattributes
