fix: normalize hour=24 to 0 in cron date parts (Node 20 Intl bug)

In Node 20, Intl.DateTimeFormat with hourCycle='h23' can return '24'
instead of '00' for midnight. This caused computeNextCronRunAt to never
match hour=0 expressions (e.g. '0 0 * * 0'), exhausting the search loop
and throwing. Normalize rawHour === 24 to 0 to fix.
