Why

Teams use Tally for release checklists, but tasks have no notion of a deadline, so people track dates in task titles ("[Fri] ship notes"). That breaks sorting and makes overdue work invisible.

What Changes

• Tasks gain an optional due_date (calendar date, no time component, interpreted in the project's time zone)
• Task listing can sort by due date and show an "overdue" badge
• Assignees get a reminder notification the morning a task is due
