A submission failed with HTTP 403 against a freshly published image. The
cause was not Alpine, which carries the current yt-dlp: it was the apk layer
being reused from an older build, so the image shipped a yt-dlp two months
behind while /healthz reported today's tag.
"A rebuild is the update" only holds if the layer is genuinely re-run, so
the image target now passes --pull --no-cache. Slower, and the only thing
that makes the release honest about what is inside it.
