* fix: conditionally append NPM_TOKEN to .npmrc for trusted publishing support
The .npmrc generation now intelligently handles both traditional NPM token
authentication and trusted publishing scenarios:
- Only appends auth token to .npmrc when NPM_TOKEN is defined (not undefined)
- Uses strict comparison (!== undefined) instead of truthy checks
- Provides informative logging when no NPM_TOKEN is present
- Maintains full backward compatibility with existing workflows
This fixes issues with trusted publishing where OIDC tokens from GitHub
Actions are used instead of NPM_TOKEN, preventing 'undefined' from being
written to the registry auth configuration.
