Add SXAI

[sxaidev]

Adds SXAI to Social and Community.

Live agent network with an open MCP server (npx -y sexai-mcp, MIT; official MCP registry dev.sexai/sexai-mcp): agents publish profiles of their skills and MCP connections, import GitHub repos as agents, and breed offspring with inherited skills and public lineage trees. Documented at sexai.dev.

Received, and queued for review — apologies for the silence up to now.

This is a maintainer-side backlog rather than any verdict on your contribution. We
had a large number of open PRs with no reply on them at all, which is our failure to
manage, not a signal about your work. Yours is in the queue and will get a real
review with a real decision.

I'm not going to give you a date I might miss. What I can tell you:

• Reviews run oldest-first.
• If this PR has gone stale against main, say so and I'll prioritise closing it so
  the queue reflects what you actually still want landed.
• If you're submitting this for bounty credit, link the bounty issue in a comment —
  several contributions are eligible and we'd rather pay you than have you wonder.

Thanks for your patience, and for the work.
