Bulk --repair on unauthenticated YouTube trips the bot-check (HTTP 429 "Sign
in to confirm you're not a bot"), after which every call fails until the IP
flag clears. Add cookie support so authenticated requests bypass it:
- --cookies FILE / --cookies-from-browser BROWSER (and $YTDLP_COOKIES /
$YTDLP_COOKIES_FROM_BROWSER for the API container), threaded into every
yt-dlp invocation (search, probe, download, repair metadata fetch).
- run_yt_dlp_get_metadata now logs yt-dlp's last stderr line (the actual 429 /
bot-check / network reason) instead of a bare exit code.
- Default --repair workers lowered 8 -> 4 (safe without cookies; raise with).
- compose: optional YTDLP_COOKIES env + commented cookies mount.
- README: how to obtain cookies (Chrome/Firefox, browser-read vs cookies.txt
export); gitignore cookies.txt.
