kiira

Set up Kiira on a project's docs. Load when installing kiira, running the first `kiira check`, scaffolding with `kiira init`, or deciding whether a `kiira.config.ts` is needed. Covers installing where the API types resolve, the only required option (`include`), the ts/tsx/js/jsx fence format in .md/.mdx, and the automatic `tsconfig.docs.json` preference.
