- README rewritten around the Controlling Architect concept (spec -> build -> report -> verify), the architect/builder agency and the channels; upstream README preserved as README.upstream.md
- install.sh: fork-native installer adapted from Darren Hinde's OAC installer. Syncs the complete .opencode payload (no registry), supports local/global/custom, skip/overwrite/backup, --source/--token/--branch/--yes/--force/--dry-run
