- Migration 0006: notes.kind ('text'|'list') + note_items (text, checked, position). Item API: add/update(toggle)/delete/reorder; PATCH note kind; note responses include kind + items[] (merged in one query alongside labels). - notes store: kind/items on Note, setKind/addItem/updateItem/deleteItem. - NoteChecklist component (toggle/add/edit/delete items); rendered read-only-ish on cards (checkboxes toggle) and editable in the editor. - Editor: convert text<->checklist (body lines become items on convert to list).
