refactor: Enforce 10-task limit and file cohesion across workflow system

- Update workflow-architecture.md: Streamline structure, enforce 10-task hard limit
- Update workflow plan.md: Add file cohesion rules, similar functionality warnings
- Update task breakdown.md: Manual breakdown controls, conflict detection
- Update task-core.md: Sync JSON schema with workflow-architecture.md
- Establish consistent 10-task maximum across all workflow commands
- Add file cohesion enforcement to prevent splitting related files
- Replace "Complex" classification with "Over-scope" requiring re-planning
