Push the current branch, ensure a PR exists, watch CI, and merge the moment all required checks are green — the 'watch the checks and merge if green' tail that /commit doesn't cover. TRIGGER WHEN: 'merge it once green', 'watch CI and merge when green', 'merge the PR once checks pass', 'enable auto-merge once checks pass', 'merge #N when green', 'push and open a PR then merge when green'. DO NOT USE WHEN: just creating a commit (use /commit), reviewing the diff (use /code-review), or the user wants to merge a red/failing PR right now (do that directly with gh, don't pretend it's green).
