magpie-pr-management-code-review

Walk a maintainer through deep, sequential code review of open pull requests on the configured <upstream> repo. Defaults to the "my reviews" queue (the union of five maintainer signals — see the Inputs table); selectors can narrow to a single PR, an area label, or a collaborator subset. Drafts an approve / request-changes / comment review per PR and posts on the maintainer's confirmation.
