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.

## 附註 {#notes}
|
|
|
|
- `stereo-to-mono` 會把兩個聲道混成單一單聲道音軌。
|
|
- `mono-to-stereo` 會把單聲道複製到左右兩個聲道。
|
|
- `swap` 會交換立體聲檔案的左右聲道。
|
|
- 輸出通常會保留輸入的容器格式。AAC 輸入會寫成 M4A，而僅能解碼但不受支援的輸入會退回 MP3。
