Pull Request Overview

This PR removes the per-commit checking functionality from the GitHub workflow, simplifying the CI pipeline to run checks only against the latest commit instead of iterating through individual commits in a PR or push.

• Removes the commit_list job that generated a list of commits to be checked
• Updates all dependent jobs to run against the current HEAD instead of individual commits
• Simplifies job matrix configurations by removing commit-based iterations
