[CLAUDE] CICD: rollback npm junction cache (giữ path filter), fix #111 fail tsc not found

Run #111 (commit 29eb5d9) FAIL với `'tsc' is not recognized` ở step Build fe-admin.
Symptoms confusing:
- VPS check: cache dir C:\npm-cache-erp\ chưa có (cold)
- Log: KHÔNG có Write-Host "cache MISS" hay "added 239 packages"
- Timing: 1.6s từ end-of-BE-build → start-of-fe-admin-build (impossible cho npm install 49s)
- Test gate (Domain 54 + Infra 17) PASS nên không phải code regression

Khả năng cao: junction Move-Item disrupted node_modules .bin/ structure HOẶC
act_runner PowerShell stream capture có quirk với cache MISS branch. Cần debug
riêng — không nên block deploy chính.

Decision:
- Rollback npm cache logic về fresh install như cũ (49s + 33s)
- GIỮ path filter on:push:paths-ignore (đây mới là win lớn nhất — 100% saving cho MD-only commit)
- Document gotcha cho session sau (sẽ thử robocopy thay vì junction, hoặc dùng act_runner cache server local)

Path filter behavior (giữ lại):
- Commit chỉ docs/MD/skill/gitignore → SKIP CI hoàn toàn (~196s/commit saved)
- Commit code OR cùng commit có code+docs → vẫn trigger (đúng)

Verify dotnet test local: 71 pass / 1s (BE không thay đổi).
