Phase 3: Add structural improvements to training schema and stages

- Add depends_on field to training schema for stage dependencies
- Add difficulty field to training schema (beginner/intermediate/advanced/expert)
- Add estimated_time_minutes field to training schema
- Add structural fields to stage1_foundation.json (beginner, 30min, no dependencies)
- Add structural fields to stage2_operations_mastery.json (beginner, 45min, depends on stage1)
- Add structural fields to stage3_ai_operations.json (intermediate, 60min, depends on stage2)
- Add structural fields to stage4_marketplace_economics.json (intermediate, 60min, depends on stage2)
- Add structural fields to stage5_expert_operations.json (advanced, 90min, depends on stage3, stage4)
- Add structural fields to stage6_agent_identity_sdk.json (advanced, 75min, depends on stage5)
