backlog-report

@zkysar1

Generates a complete sprint-planning backlog as copy-pasteable markdown: all aspirations, goals, scores, blockers, and user action items, written to {agent}/BACKLOG.md with a compact terminal summary. Use whenever the user says "show me the backlog", "give me sprint planning material", "what's in the queue", or needs pasteable content for a planning doc or standup. User-invocable AND agent-callable; valid in any mode including reader.
