Fix jlpm authentication token for npm registry

[coderabbitai]

Issue

The jlpm steps in the CI workflow are currently using GITHUB_TOKEN for authentication, but jlpm/Yarn/NPM expects NODE_AUTH_TOKEN (or YARN_NPM_AUTH_TOKEN) for registry authentication.

Problem

When packages require GitHub Packages/NPM authentication, the install and audit steps will fail because GITHUB_TOKEN is not recognized by the npm registry authentication system.

Solution

Replace GITHUB_TOKEN with NODE_AUTH_TOKEN in the environment variables for the jlpm steps in .github/workflows/ci.yml:

Lines to fix:

• Lines 52-59 (audit-prod job, jlpm install and audit steps)
• Lines 76-83 (audit-all job, jlpm install and audit steps)

Change:

env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

To:

env:
  NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
