SnapOtterandGitHub f858c4cea0 feat: clearer, disambiguated tool names across all surfaces (#520)
Renames 18 ambiguous or hard-to-search tool names so image tools self-qualify like the other modalities ("Compress" becomes "Compress Image"), and cleans up a few awkward names. Propagated across search (constants.ts), display (en.ts + 20 locales), the OpenAPI base spec + 20 locale specs, and the docs tool-page headings in 21 languages. Removes the duplicate "Normalize Audio" summary shared by the video and audio endpoints. Tool ids and routes are unchanged, so no API paths or bookmarks break.

# 壓縮影像 {#compress}
透過指定品質層級或以 KB 為單位的目標檔案大小來縮減圖片檔案大小。此工具使用迭代式二元搜尋以精準達到大小目標。
## API 端點 {#api-endpoint}
`POST /api/v1/tools/image/compress`
接受包含圖片檔案與 JSON `settings` 欄位的 multipart 表單資料。
## 參數 {#parameters}
| 參數 | 類型 | 必填 | 預設值 | 說明 |
|-----------|------|----------|---------|-------------|
| mode | string | 否 | `"quality"` | 壓縮模式:`quality``targetSize` |
| quality | number | 否 | `80` | 品質層級(1-100)。當模式為 `quality` 時使用。 |
| targetSizeKb | number | 否 | - | 以 KB 為單位的目標檔案大小。當模式為 `targetSize` 時使用。 |
## 範例請求 {#example-request}
壓縮至品質 60
```bash
curl -X POST http://localhost:1349/api/v1/tools/image/compress \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@photo.jpg" \
-F 'settings={"mode": "quality", "quality": 60}'
```
壓縮至目標大小 200 KB
```bash
curl -X POST http://localhost:1349/api/v1/tools/image/compress \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@photo.jpg" \
-F 'settings={"mode": "targetSize", "targetSizeKb": 200}'
```
## 範例回應 {#example-response}
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/photo.jpg",
"originalSize": 2450000,
"processedSize": 204800
}
```
## 備註 {#notes}
-`quality` 模式下,數值越低,檔案越小,但壓縮失真也越多。值為 80 是網頁使用的良好預設。
-`targetSize` 模式下,引擎會執行迭代壓縮,在不超過目標的前提下盡可能逼近目標。
- 輸出格式與輸入格式相符。壓縮套用於該格式的原生編碼(例如 JPEG 檔案用 JPEG 品質,WebP 檔案用 WebP 品質)。
- 若預設品質(80)可接受,可完全省略 `quality` 參數。
