feat: working E2E container stack with Node-RED + InfluxDB + Grafana
- Fix Dockerfile.e2e to install EVOLV properly in Node-RED /data/ - Add measurement node E2E test flow with scaling (4-20mA to 0-5m) - Add Grafana health check to run-e2e.sh - Guard pumpingStation demo IIFE with require.main check - All 10 EVOLV nodes load successfully in containerized Node-RED Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
