Annotate in-cooldown versions in bundle outdated output

bundle outdated still surfaces newer-but-cooldown'd versions instead of
hiding them, so the user knows an upgrade is pending rather than
silently missing. The prose form gains ", in cooldown for Nd more days"
and the table form appends "(cooldown Nd)" to the Latest column.
