Forget (F): Soft-delete shapes — close button sets forgotten:true in
Automerge doc instead of removing. Memory panel (toolbar toggle) lets
users browse and Remember forgotten shapes. Server-side forgetShape()
and rememberShape() with WebSocket handlers.
Update (U): New public updateShape(id, fields) method on CommunitySync
for programmatic field updates. Existing auto-capture unchanged.
New (N): Renamed all create/add vocabulary to new — toolbar buttons,
event names (new-shape, shape-new, shape-removed), internal functions
(newShape, newShapeElement).
