# github_project_setup.py: add `milestone close` command

> `github_project_setup.py` now has `milestone start` which bulk-transitions `status:needs-grooming` → `status:in-progress`. Add a symmetric `milestone close` command for the `complete-milestone` skill. The command should: (1) validate the milestone is open, (2) list all still-open issues (warn if any remain), (3) transition open issues from `status:in-progress` → `status:done` or close them, (4) close the milestone itself via `milestone.edit(state='closed')`, (5) print a completion summary.
