0.3.1

Assign checklist items to members.

• Each checklist item now has a member circle at its far left. Click it to assign that item to a Sync Deck member (or leave it Unassigned). Assigned items show the member's avatar; unassigned show an empty circle.
• The assignment is stored per item inside the note (as a hidden comment), so it syncs across devices and leaves existing checklists unchanged.
