docs: a list is the fourth append-only shape (V-453)

An add and a crossing-off run at the top of actionNote, next to task
capture and before the embedding is paid for; the read-back is a query
source sitting beside "tasks", so the recall pass cannot answer "что мне
купить?" from an old note about the shop.

Crossing off one item claims the turn only when the list actually holds
that item, which is what keeps "купил новый ноутбук" a note.

These read h.dataStore rather than the CoreAPI: a list is local to the core
and nothing outside it writes one. The ipc seam is what it grows through
when something outside mavend needs to add to a list.

+## A list is the fourth shape
+
+Facts, notes and tasks were the three append-only shapes. `list_items` is the
+fourth (Vikunja #453): an item, a status, and a list tag.
+
+It is not a task. Milk is not work, nothing prioritises it, and the ranker must
+not start counting groceries as outstanding errands. It is not a fact either,
+because it claims nothing about the world. What it is, is a set that grows and
+shrinks.
+
+The property that makes the separate table worth it: no predicate reads a list.
+Nothing ranks it, nothing nudges about it, the digestion worker ignores it. So
+two people adding to the same list at once cost nothing — there is no order to
+disagree about and no lifecycle past crossed-off.
+
+The unique index is the tasks one, per list, and live rows only. Saying "молоко"
+twice before the shop is one line; saying it again next week, after the last one
+was crossed off, is a new line.
+
+Spoken, it is four turns: add, read back, cross one item off, cross the lot off.
+All four are matched deterministically in `internal/router/list.go` and all four
+run at stage 0, because an add and a read-back are cheap and should not depend on
+the resident model having a good turn. Crossing one item off claims the turn only
+when the list holds that item, which is what keeps "купил новый ноутбук" a note.
