fix(snippet): use <cmd>call cursor() for visual range

Problem:  Change applied in d3e495ce uses a byte-offset where a virtual
          column is expected.
Solution: Set the cursor directly through a <Cmd> mapping, while making
          sure the commands are ordered correctly by adding them to the
          type-ahead buffer.
