Instagram and TikTok extraction silently breaks whenever yt-dlp falls
behind upstream API changes, and fixing it required a manual image
rebuild each time. Updating at container start ties the fix to the Pi's
weekly reboot instead, so the extractor stays current without operator
intervention. A failed update never blocks startup, because the network
may not be up yet right after boot.
.gitattributes pins LF for shell scripts: a CRLF checkout on Windows
would make the entrypoint unrunnable inside the Linux container.
