Subject: [PATCH] fix(interactive): set monospace font + stretch on ConPTY
 terminal

The control derives Cols/Rows from arranged-size / character-cell-size; without an
explicit monospace font (as the working spike set) the cell metrics are off and the
terminal miscomputes its size, so the child TUI renders into the wrong area. Match
the spike's font/BufferSize and stretch to fill the pane.
