/**
 * Real Plugin Integration Test
 * 
 * This test verifies the real OpenClaw plugin (installed on vps.t1) 
 * can successfully connect to and report telemetry to HarborForge Backend.
 * 
 * Prerequisites:
 * - vps.t1 must have HarborForge.OpenclawPlugin installed
 * - vps.t1's OpenClaw Gateway must be running with plugin enabled
 * - Backend must be accessible from vps.t1
 * 
 * Run with: ./run-test-frontend.sh --expose-port on --test-real-plugin
