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).

# Audio Channels
Convert audio between mono and stereo layouts, or swap the left and right channels of a stereo file.
## API Endpoint
`POST /api/v1/tools/audio/audio-channels`
Accepts multipart form data with an audio file and a JSON `settings` field.
## Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| mode | string | Yes | - | Channel operation: `stereo-to-mono`, `mono-to-stereo`, `swap` |
## Example Request
```bash
curl -X POST http://localhost:1349/api/v1/tools/audio/audio-channels \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@audio.mp3" \
-F 'settings={"mode": "stereo-to-mono"}'
```
## Example Response
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.mp3",
"originalSize": 4500000,

}
```
## Notes
- `stereo-to-mono` mixes both channels into a single mono track.
- `mono-to-stereo` duplicates the mono channel to both left and right.
- `swap` exchanges the left and right channels of a stereo file.
- Output format matches the input format.
