jim800121chen 3f0175f1a9 feat(local-agent): Phase 0.5 visionA Agent — Wails 桌面 + tunnel client + 配對 UI
從 local-tool 複製出獨立的「visionA Agent」桌面應用(A3 純橋樑:
tunnel client + 配對 UI + 設定,不開 HTTP port、不做本機裝置/推論 UI)。
Bundle ID 與 local-tool 不同(com.innovedus.visiona-agent vs visiona-local),
雙 app 可共存。fork 後不主動 sync,需要時手動 cherry-pick。

Backend / Wails Go(AB1-AB13):
- internal/tunnel:6 狀態機(Idle/Connecting/Connected/Reconnecting/Failed/Stopped)
  + Pair/Unpair/Reconnect/Disconnect binding + ClientHooks event
- internal/auth:encrypted file token store(AES-GCM + scrypt + machineID
  fallback salt + 13 tests)
- internal/config:YAML validation + atomic write + 11 tests
- internal/log:ring buffer + ExportLog 升級 zip
- visionA-backend /api/pairing/exchange:SessionTokenStore + 17 new tests
- 三平台 build 驗證(macOS DMG 160 MB / Windows EXE / Linux AppImage)
- end-to-end 5 milestone 全綠(pairing → tunnel → forward → reuse 防護
  → tunnel drop failover)

Frontend / Next.js(AF1-AF7,沿用 visionA-frontend 基礎):
- AppShell + Header + TabNav(StatusView / PairView / SettingsView 三 tab)
- ConnectionStatusBadge 5 種狀態
- TokenInput regex 驗證 + 7 種錯誤 + 0.5s auto-switch 到狀態頁
- 設定頁 4 區塊(含重新配對 AlertDialog)
- agent-api.ts 封裝 Wails bindings(mock/real 雙實作)+ 90 tests

Phase 0.7 review-driven fix(Round 2):
- A1 Session fixation 防護(RotateSessionID)
- A3 mock pairing 預設改 false(必須明確 opt-in)+ startup log
- A4 Pair 失敗後 state 清理矩陣(exchange/Save/Start fail 各自終態)
- A5 Pair/Unpair/Reconnect lifecycleMu + 50 goroutine race test
- F1 重新配對次按鈕 / F2 PairView Esc cancel / F3 Wails BrowserOpenURL
  / F4 Settings draft 持久 + 未儲存 badge

驗證:agent backend go test -race -count=3 ./... 4 packages 全綠 /
agent frontend pnpm test 119 tests 全綠
