Add Node.js New Relic agent with an on/off switch via NEW_RELIC_ENABLED in .env. Uses a preload script (-r newrelic-preload.js) so the agent loads before all other modules. Configured entirely through environment variables — no newrelic.js config file needed. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
