chore(deps): upgrade docs dependencies for Astro 6 (DOCSDEV-60)

- astro 5.x -> 6.x, starlight 0.37 -> 0.38, markdown-remark 6.x -> 7.x
- docs-design-system 0.11 -> 0.12, starlight-versions 0.6 -> 0.8
- starlight-links-validator 0.19 -> 0.23, mermaid 11.12 -> 11.14
- Migrate i18n collection to use i18nLoader (Astro 6 requirement)
- Pass explicit sidebar options to starlightFullViewMode for Zod compat
