v0.9.1-pre

• A click in the editor no longer pulls the cursor onto the state's name. Sprotty fires its
  diagram selection listener for selections the server sends as well as for clicks, so the cursor
  sync's selection was answered with diagram/openInTextEditor and moved the editor cursor onto the
  selected element. Cursor-driven selections are now marked preventOpenSelection; clicking in the
  diagram still reveals the source when keith-vscode.diagram.selectText is on. The server cursor
  suite checks that no reveal follows a cursor request.
• A running simulation keeps your zoom. Every tick relays the diagram out to move the
  highlighting, and klighd-core refits the diagram after each model update because "Resize To Fit
  on Refresh" defaults to on and has had no switch since the sidebar went. Model updates that arrive
  while a simulation is running are now applied without the refit, so the viewport stays where you
  put it; the first layout after start and everything outside a simulation fit as before.
