Walkthrough

This pull request extends OpenEuler OS support across Node.js distribution installation scripts. Two OpenEuler container images were added to CI testing workflows, and RPM system detection logic was updated across all setup scripts to recognize OpenEuler systems as valid RPM-based environments alongside existing Red Hat and Amazon Linux checks.

Changes

Cohort / File(s)	Summary
CI Configuration .github/workflows/ci.yaml	Added OpenEuler 22.03-lts-sp4 and 24.03-lts-sp3 container images to the rpm job test matrix.
