Glab Cli

GitLab CLI (`glab`) reference and workflow for repository, merge request, issue, CI/CD, release, and API operations across GitLab.com and self-managed or dedicated instances. Use when Codex needs to run or explain `glab` commands, usually by relying on the current `glab` context first, and only falling back to `git remote -v` or explicit host and repo arguments when the target platform or repository is unclear.
