Subject: [PATCH] Fix: rename map cursor awareness field to avoid y-codemirror
 collision

y-codemirror.next uses the awareness 'cursor' field for text editor
cursor positions. Our map cursor tracker was using the same field name,
causing Invalid LatLng errors when the receiving participant tried to
render a CodeMirror cursor object as map coordinates.

Renamed to 'mapCursor' to avoid the collision.
