Forensic Local Feeder

This helper runs on the user's computer and listens on http://127.0.0.1:8787.
When the analyzer page asks this computer to feed a blocked URL, the helper downloads the media locally and uploads it to the VPS analyzer.

Run start-mac-linux.sh on macOS/Linux.
Run start-windows.bat on Windows.

The helper requires Python 3 and yt-dlp. The launcher attempts to install yt-dlp if it is missing.
Keep the terminal window open while using local-assisted downloads.
