Restore full subtask list on Weekly Task cards -- exception to the remove-on-close rule

Weekly Task cards are Peter's original assignment record and should stay
intact for reference, unlike the per-track cards (Outreach, CRM Research,
etc.) where closed items do get removed once logged. Week of 17-21 Aug
shows all 5 original subtasks again (4 Done, 1 Ongoing) alongside the
dated notes/reports narrative, which is unchanged.
