Interact with GitHub using the `gh` CLI to manage repositories, issues, pull requests, CI/CD workflow runs, and API queries. Use when the user asks to create, list, view, merge, or close pull requests and issues; check CI status or workflow run logs; query the GitHub API for repository data; or perform any GitHub operation from the command line. Covers `gh issue`, `gh pr`, `gh run`, `gh repo`, and `gh api` subcommands.
