feat(local-tool): 品牌視覺設計 + 內建模型首次啟動 seed

#8 首次啟動 seed 內建模型：
- app.go 新增 seedUserDataDir() 在 server spawn 之前執行
- 若 user data-dir 缺 models.json，從 locateBundleDataDir() 複製
  models.json + nef/ 預置模型過去
- 新增 locateBundleDataDir() / copyFile() / copyDirRecursive() helper
- user 第一次開 app 會看到 8 個 Kneron 預置 .nef 模型（kl520×5 + kl720×3）

#5 #6 #7 品牌視覺：
- 新增 branding/ 目錄存放設計資產與生成工具
  - logo.svg（向量原始稿）
  - icon-{16,...,1024}.png（10 種尺寸）
  - icon.ico（Windows 多解析度 ICO，PNG-in-ICO 格式）
  - icon.icns（macOS）
  - tools/gen_icon.go + gen_ico.go（純 Go 生成工具，未來調整 logo 用）
  - README.md + 色票表
- 部署：
  - visiona-local/build/appicon.png → Wails build 會嵌入 exe
  - visiona-local/frontend/icon.png → splash 使用
  - frontend/src/app/favicon.ico + icon.png → Next.js App Router favicon
- splash page 升級：加 logo icon + 品牌名 visionA Local + tagline Edge AI Workspace
- Wails window title: "visionA Local — Edge AI Workspace"
- wails.json productName: "visionA Local"
- Next.js metadata title + icons
- i18n: en/zh-TW 把殘留的 "Edge AI 平台" 字串改為 visionA Local 品牌
- .iss: SetupIconFile 指向 branding/icon.ico + UninstallDisplayIcon +
  ArchitecturesAllowed 改 x64compatible 修掉之前的 deprecation warning

品牌色票：
- 主色 #4F7EFF（電子藍）
- 輔色 #6EF3C5（mint 點綴）
- 深色背景漸層 #1A1F36 → #0E1222
- 警示 #FF6B6B

+# visionA Local — Branding Assets
+
+此目錄存放 visionA Local 的品牌視覺資產。
+
+## 檔案
+
+| 檔案 | 用途 |
+|------|------|
+| `logo.svg` | 向量原始設計稿（1024×1024） |
+| `icon-1024.png` | Wails build 的 appicon（會被 Wails 複製到 `visiona-local/build/appicon.png`） |
+| `icon-512.png` / `icon-256.png` / `icon-128.png` | 各尺寸 PNG 備用 |
+| `icon.ico` | Windows 多解析度 ICO（16/24/32/48/64/96/128/256，PNG-in-ICO 格式） |
+| `icon.icns` | macOS .app bundle icon |
+
+## 如何更新 logo
+
+1. 改 `logo.svg` 或改 `gen_icon.go` 的繪圖函數
+2. 跑 `go run gen_icon.go <output-dir>` 產出各尺寸 PNG
+3. 跑 `go run gen_ico.go icon.ico <png-dir> 16,24,32,48,64,96,128,256` 產 Windows ICO
+4. macOS icns 用 `iconutil`：
+   ```bash
+   mkdir icon.iconset
+   cp icon-16.png icon.iconset/icon_16x16.png
+   cp icon-32.png icon.iconset/icon_16x16@2x.png
+   cp icon-32.png icon.iconset/icon_32x32.png
+   cp icon-64.png icon.iconset/icon_32x32@2x.png
+   cp icon-128.png icon.iconset/icon_128x128.png
+   cp icon-256.png icon.iconset/icon_128x128@2x.png
+   cp icon-256.png icon.iconset/icon_256x256.png
+   cp icon-512.png icon.iconset/icon_256x256@2x.png
+   cp icon-512.png icon.iconset/icon_512x512.png
+   cp icon-1024.png icon.iconset/icon_512x512@2x.png
+   iconutil -c icns icon.iconset -o icon.icns
+   ```
+5. 部署：
+   - `cp icon-1024.png ../visiona-local/build/appicon.png` — Wails build
+   - `cp icon-256.png ../visiona-local/frontend/icon.png` — splash page
+   - `cp icon.ico ../frontend/src/app/favicon.ico` — Next.js favicon
+   - `cp icon-256.png ../frontend/src/app/icon.png` — Next.js App Router icon
+6. 重 build：`make clean-all && make exe`（Windows）或 `make clean-all && make dmg`（macOS）
+
+## 設計理念
+
+- 圓角方形背景（符合現代 app icon 容器標準）
+- 深藍漸層底（`#1A1F36` → `#0E1222`）傳達專業、科技感
+- 雙層同心圓環 = 相機鏡頭 / 視覺感測器隱喻
+- 中央「V」字形 = vision 首字母
+- 三個 pixel 點 + 右上 active indicator = Edge AI / pixel-level 運算的視覺語彙
+- 主色 `#4F7EFF`（電子藍）搭配 `#6EF3C5`（mint）點綴，避免純藍的冰冷
+
+## 色票
+
+| 用途 | HEX |
+|------|-----|
+| 主色 | `#4F7EFF` |
+| 主色亮色 | `#6EA8FF` |
+| 點綴 | `#6EF3C5` |
+| 深色背景頂 | `#1A1F36` |
+| 深色背景底 | `#0E1222` |
+| 警示 | `#FF6B6B` |
+| 中性灰 | `#8890B0` |
