nodeenv is a Python package that downloads a pre-built Node.js binary —
no apt repos, no compilation, guaranteed to work in python:3.12-slim.
The 'node' binary is linked into /usr/local/bin so yt-dlp can find it.
With Node.js available the web client works fully (37 formats) and can
solve YouTube's n-challenge that every other approach was failing on.
