[Copilot]

• Analyze current repository state and identify version update requirements
• Verify current build and test processes work correctly
• Update checkout action from v2 to v4 in all workflow files
• Update setup-node action from v1 to v4 in workflows that use it
• Update Node.js version from 10.15.3 to 20.x in workflows
• Update .nvmrc file to match new Node version
• Verify all tests still pass after updates
• Verify linting still passes after updates

Changes Made:

✅ Updated all 3 workflow files:

• draft-release.yml: Updated checkout@v2 → checkout@v4
• feature-build.yml: Updated checkout@v2 → checkout@v4, setup-node@v1 → setup-node@v4, Node 10.15.3 → 20.x
• publish-artificats.yml: Updated checkout@v2 → checkout@v4, setup-node@v1 → setup-node@v4, Node 10.15.3 → 20.x

✅ Updated .nvmrc: Changed from v10.15.3 to 20.x

✅ Verified functionality: All tests pass (17/17), linting passes, and coverage requirements are met (96%+ across all metrics)

Summary:
Successfully upgraded GitHub Actions to use modern versions:

• Checkout action: v2 → v4
