The parameterless MapMcp() overload did not register the endpoint
correctly at the /mcp path. Changed to MapMcp("/mcp") which
successfully registers the MCP Streamable HTTP endpoint.
Verified:
- POST /mcp with initialize request returns valid MCP response
- tools/list returns all 10 NexusMcpTools
- Health check passes
