New Alacritty windows should follow the standard macOS behavior of cascading new windows. This provides an obvious visual feedback to the user than a new window was created and also makes it much easier to manipulate the windows.

From the NSWindowController shouldCascadeWindow docs:

Cascading in relation to other document windows means having a slightly offset location so that the title bars of previously displayed windows are still visible.

Besides NSWindowController, the NSWindow class also provides cascadeTopLeftFromPoint.
