feat(task): model the reader's own weekly and monthly tasks

A task is a period that rolls on the game's reset and a measure that
fills it: days ticked, or a number against a target. Its status is the
goal status shape, so the dailies strip treats it like any other item.
Its ids get their own reserved space, as do the built-ins to come.
