review: add retry logic for npm ci command to handle network issues

Implement shell-based retry logic (3 attempts with 5-second delays) for
npm ci command to handle temporary network issues without adding external
dependencies. This improvement was requested during code review to make
the workflow more resilient to transient failures.

Continues with existing npm install approach while adding robustness
for dependency installation in GitHub Actions environment.
