Add Not Human Search and AI Dev Jobs MCP servers (#109)

* Add Not Human Search and AI Dev Jobs MCP servers

- Not Human Search: AI tool discovery engine with 8,600+ tools and MCP servers (https://nothumansearch.ai/mcp)
- AI Dev Jobs: AI/ML job search across 5,500+ curated roles from 280+ companies (https://aidevboard.com/mcp)

Both are HTTP (streamable-http) transport, no authentication required, read-only.

* Refresh NHS + AI Dev Jobs server.json descriptions

Both entries' descriptions had drifted from reality:

- Not Human Search claimed "8,600+ AI tools" (likely a copy-paste from
  AI Dev Jobs' job count) — NHS actually indexes ~1,962 agent-ready
  sites. Bumped to "1,900+ agent-ready sites" and enumerated the new
  tools (10 now — recent_additions, find_mcp_servers, verify_mcp,
  list_categories, get_top_sites on top of the original 5).

- AI Dev Jobs claimed "5,500+ roles from 280+ companies" — actual live
  numbers are 8,618 / 513 / 569 sources. Bumped to round-down floors
  (8,600+ / 510+) and enumerated the new tools (9 now — trending
  companies, posted-within-days, enriched stats). Also fixed a broken
  repo link: github.com/unitedideas/aidevboard → ai-dev-jobs.

Validates via npm run validate on both. PR #109 on mcpmux/mcp-servers
picks these up automatically.
