Subject: [PATCH] feat(mcp): add Nimble to MCP registry

Adds Nimble (web search, SERP, and site extraction) to the curated
MCP server discovery list, alongside the other Search category
entries (Brave Search, Exa, Tavily).

Uses the documented streamable HTTP MCP endpoint
(https://mcp.nimbleway.com/mcp); the legacy /sse endpoint referenced
in older docs now returns 410 Gone.
