Pull request: !`gh pr view --json number,title,url,isDraft,mergeable,mergeStateStatus 2>&1 || true` 1. No open pull request for this branch: say so and stop. 2. `gh pr checks --watch` until every check settles. It exits non-zero on failure, so allow that and read the result rather than treating it as a crash. 3. Green: `gh pr merge --squash --delete-branch`. Red: stop, name the failing check and the reason, and merge nothing. Do not retry, do not fix, do not merge past a failure. 4. A draft PR, a merge conflict, or a blocked merge state stops you too. Report which it is. 5. Report whether it merged, and the URL.
