Dependency Health Check

Format: Check the health of your project's npm dependencies.

Steps:

1. Run npm audit → Are there security vulnerabilities?
2. Run npm outdated → Are there outdated packages?
3. Check package.json:
   - Are there packages you don't know the purpose of?
   - Are there packages with overlapping functionality? (Two HTTP libraries? Two date libraries?)
   - Are there packages used only once? (Can you remove them and write a few lines of code instead?)
