SnapOtter d24e244af4 docs: organize tool pages by modality under /tools/<modality>/
Move all 157 tool pages into image/video/audio/pdf/data subfolders so URLs read /tools/<modality>/<id> (e.g. /tools/image/crop). Nest the image sub-categories under an Image group in the sidebar so the nav reads by modality. Add public/_redirects (301, clean + .html forms) mapping every old flat /tools/<id> URL to its new path so inbound links keep working. Rewrite all internal /tools links. Verified with a clean docs build (no dead links).

# Compress Video
Shrink video file size using configurable compression strength and optional resolution downscaling.
## API Endpoint
`POST /api/v1/tools/video/compress-video`
Accepts multipart form data with a video file and a JSON `settings` field. This is an async endpoint - it returns `202 Accepted` immediately and progress is streamed via SSE at `GET /api/v1/jobs/{jobId}/progress`.
## Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| quality | string | No | `"balanced"` | Compression strength: `light`, `balanced`, `strong` |
| resolution | string | No | `"original"` | Output resolution: `original`, `1080p`, `720p`, `480p` |
## Example Request
```bash
curl -X POST http://localhost:1349/api/v1/tools/video/compress-video \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@clip.mp4" \
-F 'settings={"quality": "strong", "resolution": "720p"}'
```
## Example Response
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"async": true
}
```
## Notes
- The `light` preset preserves near-original quality. The `strong` preset reduces file size aggressively at the cost of visual fidelity.
- Downscaling resolution (e.g. from 4K to 720p) compounds with compression for significant size reduction.
- Progress updates are available via SSE at `GET /api/v1/jobs/{jobId}/progress` until the job completes.
