Add standalone topology MCP with skill, scopes UI, and opt-in live sync.

Splits canvas/Fabric tools into netx-topology-mcp, documents install and a companion Cursor skill, lets API keys grant ne:write explicitly, and adds optional topology live sync so operators can watch agent drawing without constant polling.
