chore(docs): upgrade dependencies from PRs #923 and #926

Combine Renovate PRs #923 (minor dependency updates) and #926 (eslint major bump):
- Upgrade Next.js from 16.1.7 to 16.2.0 and related packages
- Update fumadocs (core/mdx/ui) to latest patch versions
- Bump Tailwind CSS 4.1.18 → 4.2.2 with supporting packages
- Update React 19.2.3 → 19.2.4 and related dependencies
- Update utilities: prettier, postcss, zod, wrangler, and others

Note: Skipped eslint 9 → 10 major bump due to upstream compatibility issues with
@typescript-eslint/utils (used by eslint-config-next). Will wait for typescript-eslint 9.x.

Verified: pnpm lint and Next.js build (all 144 pages generated successfully).
