Security: Update Node.js engine requirement

[sammons-mechanic]

Summary

The project currently specifies "engines": { "node": "8.x.x" } in package.json, which is severely outdated.

Node.js 8.x reached End of Life on December 31, 2019 and no longer receives security patches.

Current State

• Many dependencies have dropped Node.js 8 support
• Modern security patches are unavailable
• TypeScript and Mocha latest versions require Node.js 18+

Recommended Actions

1. Update package.json to specify Node.js 18 or 20 LTS:

   "engines": {
     "node": ">=18.0.0"
   }

2. Update Dockerfile to use a modern Node.js base image
3. Test the application with the updated Node.js version
4. Update any CI/CD configurations

Impact

This change is a prerequisite for most other dependency upgrades. Many security patches are only available in packages that require Node.js 16+.
