Weekly chores like 2,100 activity points are a number, not a count of
days, and monthly ones need a month. The status shape now carries its
measure and period start, so tasks can reuse it whole.

Some events want five days out of seven, not every day. The goal is the
reader's input, recomputed from the day log on every read, so backfills
and week rollovers need no bookkeeping. An unreadable stored goal reads
as none instead of being stripped, so a newer shape survives an older
bundle.
