root 65fd71dc0d fix(workers): yt-dlp argv injection — scheme check + -- separator ...

The url passed to yt-dlp is user-controllable (via /api/capture). Any
string starting with '-' would be parsed as a flag (e.g.
--config-location=/etc/passwd). Mitigations:
1. Validate scheme is http(s) and hostname is present before subprocess.
2. Pass `--` to yt-dlp so it stops flag parsing before the positional
   URL.
