Hourly prune sorted non-draft releases by createdAt, but nearly every
orca-hourly release shares one createdAt from bulk import. At the retain
cap, stable sort + reverse put the newest release past the window and
immediately deleted it with --cleanup-tag.
Sort by publishedAt (tagName as tie-break) and hard-skip the tag this run
just published so prune cannot self-delete.
