Updated foundation and tool-to-article links
- The site moved to Next.js 16 and React 19. The project security audit went from eight known vulnerabilities, one of them critical, to none.
- An interface layer no page was using was removed along with 44 unused dependencies; the production total dropped from 56 packages to 11.
- Every tool page now points to the articles covering that task, with real titles and summaries. The homepage lists six; the others, three.
