Sweeps every surface of the MockServer GitHub repository and the build pipeline to confirm nothing is outstanding and everything is clean and up to date. Covers issues, pull requests, all three GitHub security-alert types, the Dependabot updater's own health, GitHub Actions, Buildkite, branches and worktrees, discussions, releases, and published-artifact parity. Use when the user says "check GitHub", "anything outstanding", "is everything clean", "audit the repo", "check the build pipeline", "housekeeping", or before cutting a release.
