Add New Relic APM monitoring integration

- Install newrelic package (v13.6.6) and @newrelic/native-metrics
- Add 'import newrelic' as first import in src/mcp/index.ts
- Update dev script to use --env-file=.env for environment variables
- Configure for ES modules support with environment-based config

New Relic will monitor Express routes, track performance metrics,
and capture errors when NEW_RELIC_LICENSE_KEY is set.
