Migrate website to Docusaurus

[thesurenk]

Description

Our current website is built with Hugo. To modernize the developer experience and better integrate documentation, we should migrate the site to Docusaurus.

Tasks:

• Set up a new Docusaurus project scaffold
• Port existing content (pages, blog, docs) from Hugo to Docusaurus structure
• Recreate site navigation, menus, and sidebar configuration
• Apply theming/branding to match existing design (or improve if needed)
• Configure site search (Algolia DocSearch or built-in)
• Set up build and deployment pipeline (GitHub Pages / Netlify / Vercel / custom)
• QA all pages (links, images, SEO metadata, mobile responsiveness)
• Update project documentation (README, contribution guide)

Acceptance Criteria:

• Website runs fully on Docusaurus with all current content migrated.
• Theming and navigation are consistent with current branding.
• Build/deployment process is automated and documented.
• Old Hugo setup is removed once migration is stable.

Notes:
Docusaurus provides better long-term support for developer docs and a stronger ecosystem for versioned documentation, plugins, and search.
