fix: GHA CI status check

[mjun0812]

Fix: PR status check cannot fetch correct status from CI workflow using matrix strategy.

[Copilot]

Pull Request Overview

This PR fixes an issue with the GitHub Actions CI status check when using a matrix strategy by adding a new job to inspect the results of dependent jobs.

• Introduces a "ci-check" job that depends on the "ci" job.
• Uses conditional steps to exit with a failure status if any job fails or is cancelled, and with success if all jobs pass or are skipped.

• [nitpick] Add a comment explaining the purpose of using 'if: always()' with this job to ensure reviewers understand that it is meant to always run regardless of previous job statuses.
