[CLAUDE] Docs: Session 17 wrap-up — PE Workflow V2 end-to-end consolidation

User chốt MD wrap-up Session 17 (13 commit từ c847dc0 → de0f38d) — PE
Workflow V2 schema + Service wire + UX iteration đầy đủ.

MD updates:
- STATUS.md — header counts (24 mig, 58 tables, 81 test, 43 gotcha) +
  Recently Done row consolidate Session 17 wrap-up (gộp 4 row iter cũ
  thành 1 row tổng, không cắt narrative quan trọng)
- HANDOFF.md — TL;DR Session 17 + Chunk E (Designer iter + State
  machine + Service wire + UX) + Pending Session 18+
- CLAUDE.md — count (22→24 mig, 77→81 test) + V2 schema overview
- changelog/migration-todos.md — section ✅ Session 17 done với 7 task
  ticked + Defer Session 18+ explicit
- database/schema-diagram.md — §14 ApprovalWorkflow V2 schema (3 bảng
  + 2 column PE + state transitions + Service branch + Designer
  constraints + match approver V2 vs V1 table)
- gotchas.md — +#42 Dual schema branch + #43 Step.Order ≠ index 0-based
- skill contract-workflow — +section "Phase 9+ done Mig 22-24" với V2
  spec + Service branch + match logic table + Designer constraints +
  UX V2-aware + Defer Session 18+
- changelog/sessions/2026-05-08-1100-pe-workflow-v2-end-to-end.md (NEW)
  — full session log với 13 commit timeline + stats + gotchas + pending

Memory:
- project_solution_erp.md — entry Session 17 wrap-up đầy đủ (KHÔNG tạo
  file feedback mới — decisions specific cho project, không reusable
  cross-project per §9.5 anti-pattern)

Verify:
- 81 test pass (58 Domain + 23 Infra) — không thay đổi sau wrap-up
- 0 BE error
- 2 FE builds OK (đã verify ở các commit trước)
- Quy tắc consolidate §6.5: KHÔNG cắt narrative, chỉ phân tầng + remove
  duplicate. Session 17 row dài cố ý — cover full 13 commit context cho
  Session 18+ đọc lại.
