SnapOtterandGitHub 4963ab3bbd feat(docs-i18n): translate all documentation into 20 languages
All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

## Notes {#notes}
- 接受兩個檔案欄位:`file`(必填,主要截圖)及 `backgroundImage`(選填,當 `backgroundType``image` 時使用)。
- 支援 HEIC、RAW、PSD 及 SVG 輸入格式(自動解碼)。
- 陰影預設對應到特定的數值:
- `subtle`:模糊 20、offsetY 4、不透明度 20%
- `medium`:模糊 40、offsetY 10、不透明度 35%
- `dramatic`:模糊 80、offsetY 20、不透明度 50%
- 社群媒體預設會使用 `contain` 模式將最終輸出調整為符合目標尺寸:
- `twitter`1600x900
- `linkedin`1200x627
- `instagram-square`1080x1080
- `instagram-story`1080x1920
- `facebook`1200x630
- `producthunt`1270x760
- 裝置外框(`iphone``macbook``ipad`)會在影像周圍套用硬體邊框,並略過 `borderRadius` 設定。
- 當需要透明度時(陰影、圓角、裝置外框或透明背景),即使選取了 `jpeg`,輸出也會強制為 PNG。
- 影像背景在 pipeline/批次模式中不支援。
