Greptile Summary

This PR adds an appName field to the MongoClient constructor options in the Node.js MongoDB Atlas query template, correctly tagging the connection as devrel-integration-atlas-appwrite-node for Atlas monitoring and profiling.

• Adds appName: 'devrel-integration-atlas-appwrite-node' to identify Node.js traffic correctly in Atlas dashboards — the value matches the runtime and template.

Confidence Score: 5/5

Safe to merge — a single-line additive change with no logic or data-path modifications.

The change only adds a metadata string to the MongoClient options. The appName value correctly reflects the Node.js runtime and template name, and the rest of the connection setup is untouched.

No files require special attention.
