fix(setup): dynamic FK cleanup, remove normalizeName coupling

- delete-cli-agent.ts discovers tables with agent_group_id dynamically
  instead of hardcoding a list
- cli-agent step emits FOLDER in its status block so setup/auto.ts
  reads it from the step result instead of re-deriving via normalizeName
