Docs consolidated: README, AGENTS, HANDOVER, CHECKLIST at the root; PLAN, DOCMAP, ENVIRONMENT-FACTS, PAPERCLIP-API-NOTES, OPEN-ISSUES, FALLBACK-OMA, WHAT-WE-ARE-BUILDING under docs/. DOCMAP names the one home for each. The closed project's copies now carry a 'Superseded' banner pointing here, so there are not two versions of anything.
