Docs AEO, homepage redesign, and MCP guides

[buddies2705]

Summary

• Add AEO infrastructure for docs.bitquery.io: reusable <FAQ /> component with FAQPage JSON-LD on 50 pages, post-build TechArticle JSON-LD (~940 pages), robots.txt, curated llms.txt, generated llms-full.txt, nginx blog redirect + HSTS, and CI build workflow with full git history for accurate dates.
• Expand MCP documentation with Cursor, Claude Desktop, Windsurf, and trading-agent setup guides; wire redirects from legacy /docs/usecases/MCP/* paths and footer link.
• Rebuild the V2 docs homepage (command palette, search, sections, light-mode contrast fixes) and ignore local .claude/ settings in git.

Test plan

• npm run build passes with no broken links or anchors
• Verify /llms.txt, /llms-full.txt, and /robots.txt in production build output
• Spot-check FAQ accordion + JSON-LD on Uniswap API, MCP server, Polymarket, and Trading Data Overview pages
• Confirm homepage renders in light and dark mode (video play, card hovers, hero code panel contrast)
• Confirm /blog/ 301 redirects to bitquery.io/blog/ in Docker/nginx deploy
• Verify MCP redirects: /docs/usecases/MCP/cursor/ → /docs/mcp/cursor/
