120 columns is the maximum width that the Rovo Dev chat box can expand to. After that, there is just empty space.

Description

Fixes the maximum width of the Rovo Dev terminal window to 120 columns. The Rovo Dev chat box can't be wider than 120 columns. Making the window any larger is simply wasting space. A user might have width set to 0.33 which is less than 120 columns on a small monitor but greater than 120 on a larger external monitor. This ensures that on the large monitor, the window will fill up as much space as it can without wasting space.
