Status values: `PENDING` → `PROCESSING` → `COMPLETED` (or `FAILED`)

## Execution Flow (Follow Exactly)

1. **Parse args** → extract video path/URL, options
2. **Download remote video** (if URL): `yt-dlp "URL" -o /tmp/verging-video-enhancement/input.mp4`
3. **Get duration** → `ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 video.mp4`
4. **Trim if needed** (--start/--end or duration > 30s):
   ```bash
   ffmpeg -i input.mp4 -ss <start> -to <end> -c:v libx264 -c:a aac /tmp/verging-video-enhancement/trimmed.mp4
   ```
5. **Check credits** → GET /api/v1/auth/me (need duration × 3 normal or ×5 HD)
6. **Upload video** → POST /upload-video (Form Data) → PUT to presigned URL
7. **Create job** → POST /video_enhance/create-job (Form Data)
8. **Poll status** → GET /jobs/list-jobs?job_ids=X every 5 seconds until COMPLETED
9. **Return/download result** → show result_url, optionally curl download

## Critical Notes

- **Use `Authorization: ApiKey <key>` (recommended)** — `Bearer <key>` also works
- **`/upload-video` uses Form Data (`-F`)** — NOT JSON
- **`/video_enhance/create-job` uses Form Data (`-F`)** — NOT JSON, no file upload needed
- **Max video duration: 30 seconds** — trim longer videos first
- **Temp directory:** `/tmp/verging-video-enhancement/`
- If yt-dlp unavailable, ask user to download video manually

## Credit Consumption

| Mode | Cost |
|------|------|
| Normal | 3 credits/second |
| HD | 5 credits/second |

## Privacy & Security
