[CLAUDE] Docs+Tests: chốt final session 5 — 77 test (Phase 3 mini PE WF) + 3 gotcha CI + 8 doc updates

Final close session 5 — bao gồm:

==== Tests Phase 3 mini (NEW) ====
tests/SolutionErp.Infrastructure.Tests/Application/PeWorkflowAdminTests.cs
- 6 test CreatePeWorkflowDefinitionCommandHandler:
  - First version → IsActive=true, Version=1, ActivatedAt set
  - Second version same Code → auto-increment v2 + deactivate v1 (atomic)
  - Different EvaluationType (A vs B) → independent active state
  - Persists steps ordered by Order field
  - Persists approvers per step
  - Third version → v1 + v2 deactivate, v3 active

Total tests: 71 → 77 pass / ~2s (54 Domain + 23 Infra).
Skip Phase 3 full (UpsertOpinion + Budget link validation) — cần
Identity UserManager DI helper, defer session sau.

==== 3 gotcha CI mới (#39 #40 #41) ====
- #39 act_runner github.com TCP timeout 21s → manual checkout fix (run #108/#109 fail, #110 pass)
- #40 npm junction cache `tsc not found` after Move-Item — rolled back, hypothesis nested junctions
  trong node_modules disrupt .bin/ paths. TODO debug session sau với robocopy hoặc act_runner cache.host
- #41 Gitea Actions paths-ignore behavior — workflow file change vẫn trigger (correct), commit
  MD-only skip 100% (verify 512880c → no run #113)
+ Checklist debug bug mới items 18-20 referencing 3 gotcha trên.

==== Doc updates (8 file) ====
- STATUS.md: header Phase 8 update + 3 row Recently Done CI fixes + cumulative test 71→77
- HANDOFF.md: TL;DR + CI optimize section + Phase status + gotcha count 38→41
- migration-todos.md: Phase 8 §E updated với Phase 3 mini done + CI fixes
- rules.md §7 Testing: rewrite full — stack + test pyramid + quy tắc bổ sung mỗi feature +
  workflow user end-of-task (`dotnet test` local trước push) + CI gate behavior
- architecture.md §11: update test pyramid + phased priority + CI optimization sub-section
  (3 fix manual checkout / path filter / npm cache rollback) + tốc độ deploy table
- gotchas.md: + #39 #40 #41 đầy đủ (triệu chứng + nguyên nhân + fix + reference)
- ef-core-migration SKILL: Phase 8 update note thêm CI fixes + 77 test
- CLAUDE.md root: test count 71→77 + folder structure + CI/CD pipeline 3 fix section
- memory project_solution_erp.md: session 5 summary + workflow user mới
- session log 2026-04-29-2300-chot-final-ci-tests-gotchas.md (NEW — 9 section detail)

==== Skill audit cron ====
`solution-erp-skill-audit-monthly` next fire 2026-05-01 (2 ngày sau).
Cron survives across sessions (setup commit b904a25). Khi fire sẽ:
- Cross-check 6 skill với STATUS/gotchas/migration-todos
- Auto-refresh stale + đề xuất add/archive cho human approve
- Log vào docs/changelog/skill-audit-2026-05.md
- ABORT nếu repo dirty

==== Verify ====
- dotnet test SolutionErp.slnx → 77 pass / ~2s (54 Domain + 23 Infra)
- git status clean sau commit này
- CI: commit này chứa code (test + workflow) → trigger CI test gate
