feat(phase6): implement end-to-end enterprise scenario validation (U15)

- Add goal-driven agent skill config and pipeline config
- Add 9 E2E integration tests covering all 7 capabilities:
  - SC1: Goal-driven SEO analysis (GoalPlanner→PlanExecutor→PlanChecker→ExperienceStore)
  - SC2: Knowledge Q&A with system operation (MultiSourceRAG)
  - SC3: Workflow with approval (WorkflowStore + approval node)
  - SC4: Self-evolution experience accumulation (ExperienceStore→PitfallDetector→PathOptimizer)
  - SC5: Parallel execution efficiency verification
  - SC6: Skill registry integration (capabilities, versions, health)
  - Cross-capability: Plan+Experience+Pitfall, Review+Experience, RAG+Workflow
- All 2472 tests passing (9 integration + 2463 unit)
