feat: Improve delete API with clear hard delete option

- Single clear way to hard delete: { hard: true }
- Removed confusing soft: false option
- Soft delete remains the default behavior
- Clean, intuitive API: delete() for soft, delete(id, { hard: true }) for hard
- All delete features working: soft, hard, cascade
