fix(sprint83b): title_conflict_check agent delegation bug

- title_conflict_check.yml: replace identity.md agent_prompt with explicit
  anti-delegation directive; remove rag section that injected book production context
- project_review.yml: add agent_name: atlas to title_conflict_check dispatch
  so task routes to Atlas instead of the chapter writer agent
