What is project-roadmap-manager?
Create and maintain a repository-root ROADMAP.md as the single source of truth for project milestones and accepted plans. Use when bootstrapping any new project, accepting/completing a plan, defining or updating milestone/version roadmaps, marking milestones as reached/changed/de-scoped, or answering where roadmap and milestone status should be referenced.
